+ * Cords are immutable character strings.  A number of operations
+ * on long cords are much more efficient than their strings.h counterpart.
+ * In particular, concatenation takes constant time independent of the length
+ * of the arguments.  (Cords are represented as trees, with internal
+ * nodes representing concatenation and leaves consisting of either C
+ * strings or a functional description of the string.)
+ *
+ * The following are reasonable applications of cords.  They would perform
+ * unacceptably if C strings were used:
+ * - A compiler that produces assembly language output by repeatedly
+ *   concatenating instructions onto a cord representing the output file.
+ * - A text editor that converts the input file to a cord, and then
+ *   performs editing operations by producing a new cord representing
+ *   the file after each character change (and keeping the old ones in an
+ *   edit history)
+ *
+ * For optimal performance, cords should be built by
+ * concatenating short sections.
+ * This interface is designed for maximum compatibility with C strings.
+ * ASCII NUL characters may be embedded in cords using CORD_from_fn.
+ * This is handled correctly, but CORD_to_char_star will produce a string
+ * with embedded NULs when given such a cord.
+ *
+ * This interface is fairly big, largely for performance reasons.
+ * The most basic constants and functions:
+ *
+ * CORD - the type of a cord;
+ * CORD_EMPTY - empty cord;
+ * CORD_len(cord) - length of a cord;
+ * CORD_cat(cord1,cord2) - concatenation of two cords;
+ * CORD_substr(cord, start, len) - substring (or subcord);
+ * CORD_pos i;  CORD_FOR(i, cord) {  ... CORD_pos_fetch(i) ... } -
+ *    examine each character in a cord.  CORD_pos_fetch(i) is the char.
+ * CORD_fetch(int i) - Retrieve i'th character (slowly).
+ * CORD_cmp(cord1, cord2) - compare two cords.
+ * CORD_from_file(FILE * f) - turn a read-only file into a cord.
+ * CORD_to_char_star(cord) - convert to C string.
+ *   (Non-NULL C constant strings are cords.)
+ * CORD_printf (etc.) - cord version of printf. Use %r for cords.

+/****************************************************************************
+C++ Interface to the Boehm Collector
+
+    John R. Ellis and Jesse Hull
+
+This interface provides access to the Boehm collector.  It provides
+basic facilities similar to those described in "Safe, Efficient
+Garbage Collection for C++", by John R. Ellis and David L. Detlefs
+(ftp://ftp.parc.xerox.com/pub/ellis/gc).
+
+All heap-allocated objects are either "collectible" or
+"uncollectible".  Programs must explicitly delete uncollectible
+objects, whereas the garbage collector will automatically delete
+collectible objects when it discovers them to be inaccessible.
+Collectible objects may freely point at uncollectible objects and vice
+versa.
+
+Objects allocated with the built-in "::operator new" are uncollectible.
+
+Objects derived from class "gc" are collectible.  For example:
+
+    class A: public gc {...};
+    A* a = new A;       // a is collectible.
+
+Collectible instances of non-class types can be allocated using the GC
+(or UseGC) placement:
+
+    typedef int A[ 10 ];
+    A* a = new (GC) A;
+
+Uncollectible instances of classes derived from "gc" can be allocated
+using the NoGC placement:
+
+    class A: public gc {...};
+    A* a = new (NoGC) A;   // a is uncollectible.
+
+The new(PointerFreeGC) syntax allows the allocation of collectible
+objects that are not scanned by the collector.  This useful if you
+are allocating compressed data, bitmaps, or network packets.  (In
+the latter case, it may remove danger of unfriendly network packets
+intentionally containing values that cause spurious memory retention.)
+
+Both uncollectible and collectible objects can be explicitly deleted
+with "delete", which invokes an object's destructors and frees its
+storage immediately.
+
+A collectible object may have a clean-up function, which will be
+invoked when the collector discovers the object to be inaccessible.
+An object derived from "gc_cleanup" or containing a member derived
+from "gc_cleanup" has a default clean-up function that invokes the
+object's destructors.  Explicit clean-up functions may be specified as
+an additional placement argument:
+
+    A* a = ::new (GC, MyCleanup) A;
+
+An object is considered "accessible" by the collector if it can be
+reached by a path of pointers from static variables, automatic
+variables of active functions, or from some object with clean-up
+enabled; pointers from an object to itself are ignored.
+
+Thus, if objects A and B both have clean-up functions, and A points at
+B, B is considered accessible.  After A's clean-up is invoked and its
+storage released, B will then become inaccessible and will have its
+clean-up invoked.  If A points at B and B points to A, forming a
+cycle, then that's considered a storage leak, and neither will be
+collectible.  See the interface gc.h for low-level facilities for
+handling such cycles of objects with clean-up.
+
+The collector cannot guarantee that it will find all inaccessible
+objects.  In practice, it finds almost all of them.
+
+
+Cautions:
+
+1. Be sure the collector has been augmented with "make c++" or
+"--enable-cplusplus".
+
+2.  If your compiler supports the new "operator new[]" syntax, then
+add -DGC_OPERATOR_NEW_ARRAY to the Makefile.
+
+If your compiler doesn't support "operator new[]", beware that an
+array of type T, where T is derived from "gc", may or may not be
+allocated as a collectible object (it depends on the compiler).  Use
+the explicit GC placement to make the array collectible.  For example:
+
+    class A: public gc {...};
+    A* a1 = new A[ 10 ];        // collectible or uncollectible?
+    A* a2 = new (GC) A[ 10 ];   // collectible.
+
+3. The destructors of collectible arrays of objects derived from
+"gc_cleanup" will not be invoked properly.  For example:
+
+    class A: public gc_cleanup {...};
+    A* a = new (GC) A[ 10 ];    // destructors not invoked correctly
+
+Typically, only the destructor for the first element of the array will
+be invoked when the array is garbage-collected.  To get all the
+destructors of any array executed, you must supply an explicit
+clean-up function:
+
+    A* a = new (GC, MyCleanUp) A[ 10 ];
+
+(Implementing clean-up of arrays correctly, portably, and in a way
+that preserves the correct exception semantics requires a language
+extension, e.g. the "gc" keyword.)
+
+4. Compiler bugs (now hopefully history):
+
+* Solaris 2's CC (SC3.0) doesn't implement t->~T() correctly, so the
+destructors of classes derived from gc_cleanup won't be invoked.
+You'll have to explicitly register a clean-up function with
+new-placement syntax.
+
+* Evidently cfront 3.0 does not allow destructors to be explicitly
+invoked using the ANSI-conforming syntax t->~T().  If you're using
+cfront 3.0, you'll have to comment out the class gc_cleanup, which
+uses explicit invocation.
+
+5. GC name conflicts:
+
+Many other systems seem to use the identifier "GC" as an abbreviation
+for "Graphics Context".  Since version 5.0, GC placement has been replaced
+by UseGC.  GC is an alias for UseGC, unless GC_NAME_CONFLICT is defined.

+// This is a revision of gc_allocator.h for SGI STL versions > 3.0.
+// Unlike earlier versions, it supplements the standard (STL) alloc.h
+// instead of replacing it.
+//
+// This is sloppy about variable names used in header files.
+// It also doesn't yet understand the new header file names or
+// namespaces.
+//
+// This assumes the collector has been compiled with -DGC_ATOMIC_UNCOLLECTABLE.
+// The user should also consider -DREDIRECT_MALLOC=GC_uncollectable_malloc,
+// to ensure that object allocated through malloc are traced.
+//
+// Some of this could be faster in the explicit deallocation case.
+// In particular, we spend too much time clearing objects on the
+// free lists.  That could be avoided.
+//
+// This uses template classes with static members, and hence does not work
+// with g++ 2.7.2 and earlier.
+//
+// Unlike its predecessor, this one simply defines
+//      gc_alloc
+//      single_client_gc_alloc
+//      traceable_alloc
+//      single_client_traceable_alloc
+//
+// It does not redefine alloc.  Nor does it change the default allocator,
+// though the user may wish to do so.  (The argument against changing
+// the default allocator is that it may introduce subtle link compatibility
+// problems.  The argument for changing it is that the usual default
+// allocator is usually a very bad choice for a garbage collected environment.)

+/*
+ * For each architecture and OS, the following need to be defined:
+ *
+ * CPP_WORDSZ is a simple integer constant representing the word size.
+ * in bits.  We assume byte addressability, where a byte has 8 bits.
+ * We also assume CPP_WORDSZ is either 32 or 64.
+ * (We care about the length of pointers, not hardware
+ * bus widths.  Thus a 64 bit processor with a C compiler that uses
+ * 32 bit pointers should use CPP_WORDSZ of 32, not 64. Default is 32.)
+ *
+ * MACH_TYPE is a string representation of the machine type.
+ * OS_TYPE is analogous for the OS.
+ *
+ * ALIGNMENT is the largest N, such that
+ * all pointer are guaranteed to be aligned on N byte boundaries.
+ * defining it to be 1 will always work, but perform poorly.
+ *
+ * DATASTART is the beginning of the data segment.
+ * On some platforms SEARCH_FOR_DATA_START is defined.
+ * The latter will cause GC_data_start to
+ * be set to an address determined by accessing data backwards from _end
+ * until an unmapped page is found.  DATASTART will be defined to be
+ * GC_data_start.
+ * On UNIX-like systems, the collector will scan the area between DATASTART
+ * and DATAEND for root pointers.
+ *
+ * DATAEND, if not "end", where "end" is defined as "extern int end[]".
+ * RTH suggests gaining access to linker script synth'd values with
+ * this idiom instead of "&end", where "end" is defined as "extern int end".
+ * Otherwise, "GCC will assume these are in .sdata/.sbss" and it will, e.g.,
+ * cause failures on alpha*-*-* with -msmall-data or -fpic or mips-*-*
+ * without any special options.
+ *
+ * STACKBOTTOM is the cool end of the stack, which is usually the
+ * highest address in the stack.
+ * Under PCR or OS/2, we have other ways of finding thread stacks.
+ * For each machine, the following should:
+ * 1) define STACK_GROWS_UP if the stack grows toward higher addresses, and
+ * 2) define exactly one of
+ *      STACKBOTTOM (should be defined to be an expression)
+ *      LINUX_STACKBOTTOM
+ *      HEURISTIC1
+ *      HEURISTIC2
+ * If STACKBOTTOM is defined, then its value will be used directly as the
+ * stack base.  If LINUX_STACKBOTTOM is defined, then it will be determined
+ * with a method appropriate for most Linux systems.  Currently we look
+ * first for __libc_stack_end (currently only if USE_LIBC_PRIVATES is
+ * defined), and if that fails read it from /proc.  (If USE_LIBC_PRIVATES
+ * is not defined and NO_PROC_STAT is defined, we revert to HEURISTIC2.)
+ * If either of the last two macros are defined, then STACKBOTTOM is computed
+ * during collector startup using one of the following two heuristics:
+ * HEURISTIC1:  Take an address inside GC_init's frame, and round it up to
+ *              the next multiple of STACK_GRAN.
+ * HEURISTIC2:  Take an address inside GC_init's frame, increment it repeatedly
+ *              in small steps (decrement if STACK_GROWS_UP), and read the value
+ *              at each location.  Remember the value when the first
+ *              Segmentation violation or Bus error is signaled.  Round that
+ *              to the nearest plausible page boundary, and use that instead
+ *              of STACKBOTTOM.
+ *
+ * Gustavo Rodriguez-Rivera points out that on most (all?) Unix machines,
+ * the value of environ is a pointer that can serve as STACKBOTTOM.
+ * I expect that HEURISTIC2 can be replaced by this approach, which
+ * interferes far less with debugging.  However it has the disadvantage
+ * that it's confused by a putenv call before the collector is initialized.
+ * This could be dealt with by intercepting putenv ...
+ *
+ * If no expression for STACKBOTTOM can be found, and neither of the above
+ * heuristics are usable, the collector can still be used with all of the above
+ * undefined, provided one of the following is done:
+ * 1) GC_mark_roots can be changed to somehow mark from the correct stack(s)
+ *    without reference to STACKBOTTOM.  This is appropriate for use in
+ *    conjunction with thread packages, since there will be multiple stacks.
+ *    (Allocating thread stacks in the heap, and treating them as ordinary
+ *    heap data objects is also possible as a last resort.  However, this is
+ *    likely to introduce significant amounts of excess storage retention
+ *    unless the dead parts of the thread stacks are periodically cleared.)
+ * 2) Client code may set GC_stackbottom before calling any GC_ routines.
+ *    If the author of the client code controls the main program, this is
+ *    easily accomplished by introducing a new main program, setting
+ *    GC_stackbottom to the address of a local variable, and then calling
+ *    the original main program.  The new main program would read something
+ *    like (provided real_main() is not inlined by the compiler):
+ *
+ *              #include "gc.h"
+ *
+ *              main(argc, argv, envp)
+ *              int argc;
+ *              char **argv, **envp;
+ *              {
+ *                  volatile int dummy;
+ *
+ *                  GC_stackbottom = (ptr_t)(&dummy);
+ *                  return(real_main(argc, argv, envp));
+ *              }
+ *
+ *
+ * Each architecture may also define the style of virtual dirty bit
+ * implementation to be used:
+ *   MPROTECT_VDB: Write protect the heap and catch faults.
+ *   GWW_VDB: Use win32 GetWriteWatch primitive.
+ *   PROC_VDB: Use the SVR4 /proc primitives to read dirty bits.
+ *
+ * The first and second one may be combined, in which case a runtime
+ * selection will be made, based on GetWriteWatch availability.
+ *
+ * An architecture may define DYNAMIC_LOADING if dyn_load.c
+ * defined GC_register_dynamic_libraries() for the architecture.
+ *
+ * An architecture may define PREFETCH(x) to preload the cache with *x.
+ * This defaults to GCC built-in operation (or a no-op for other compilers).
+ *
+ * GC_PREFETCH_FOR_WRITE(x) is used if *x is about to be written.
+ *
+ * An architecture may also define CLEAR_DOUBLE(x) to be a fast way to
+ * clear the two words at GC_malloc-aligned address x.  By default,
+ * word stores of 0 are used instead.
+ *
+ * HEAP_START may be defined as the initial address hint for mmap-based
+ * allocation.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+# The atomic_ops library (`libatomic_ops`)
+
+IN NEW CODE, PLEASE USE C11 OR C++14 STANDARD ATOMICS INSTEAD OF THIS PACKAGE.
+
+This is version 7.6.10 of libatomic_ops.
+
+
+## Download
+
+You might find a more recent/stable version on the
+[Download](https://github.com/ivmai/libatomic_ops/wiki/Download) page, or
+[BDWGC site](http://www.hboehm.info/gc/).
+
+Also, the latest bug fixes and new features are available in the
+[development repository](https://github.com/ivmai/libatomic_ops).
+
+
+## Overview
+
+This package provides semi-portable access to hardware-provided
+atomic memory update operations on a number of architectures.  These might
+allow you to write code:
+
+* That does more interesting things in signal handlers.
+
+* Makes more effective use of multiprocessors by allowing you to write
+  clever lock-free code.  Note that such code is very difficult to get
+  right, and will unavoidably be less portable than lock-based code.  It
+  is also not always faster than lock-based code.  But it may occasionally
+  be a large performance win.
+
+* To experiment with new and much better thread programming paradigms, etc.
+
+For details and licensing restrictions see the files in the "doc"
+subdirectory.
+
+
+## Installation and Usage
+
+The configuration and build scripts for this package were generated by
+Automake/Autoconf.  `./configure; make; sudo make install` in this
+directory should work.  For a more customized build, see the output of
+`./configure --help`.  To build it from the development repository,
+`./autogen.sh` should be executed first.
+
+Note that much of the content of this library is in the header files.
+However, two small libraries are built and installed:
+
+* `libatomic_ops.a` is a support library, which is not needed on some
+  platforms. This is intended to be usable, under some mild restrictions,
+  in free or proprietary code, as are all the header files.
+  See doc/LICENSING.txt.
+
+* `libatomic_ops_gpl.a` contains some higher level facilities.  This code is
+  currently covered by the GPL.  The contents currently correspond to
+  the headers `atomic_ops_stack.h` and `atomic_ops_malloc.h`.
+
+
+## Platform Specific Notes
+
+Win32/64: src/Makefile.msft contains a very simple Makefile for building
+and running tests and building the gpl library.  The core `libatomic_ops`
+implementation is entirely in header files.
+
+HP-UX/PA-RISC: `aCC -Ae` won't work as a C compiler, since it doesn't support
+inline assembly code.  Use cc.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+\`configure' configures libatomic_ops 7.6.10 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+

+   Here is a matrix of mmap possibilities:
+	mmap private not fixed
+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.

+Our intent is to make it easy to use libatomic_ops, in

+Usage:
+
+0) If possible, do this on a multiprocessor, especially if you are planning
+on modifying or enhancing the package.  It will work on a uniprocessor,
+but the tests are much more likely to pass in the presence of serious problems.
+
+1) Type ./configure --prefix=<install dir>; make; make check
+in the directory containing unpacked source.  The usual GNU build machinery
+is used, except that only static, but position-independent, libraries
+are normally built.  On Windows, read README_win32.txt instead.
+
+2) Applications should include atomic_ops.h.  Nearly all operations
+are implemented by header files included from it.  It is sometimes
+necessary, and always recommended to also link against libatomic_ops.a.
+To use the almost non-blocking stack or malloc implementations,
+see the corresponding README files, and also link against libatomic_gpl.a
+before linking against libatomic_ops.a.
+
+OVERVIEW:
+Atomic_ops.h defines a large collection of operations, each one of which is
+a combination of an (optional) atomic memory operation, and a memory barrier.
+Also defines associated feature-test macros to determine whether a particular
+operation is available on the current target hardware (either directly or
+by synthesis).  This is an attempt to replace various existing files with
+similar goals, since they usually do not handle differences in memory
+barrier styles with sufficient generality.
+
+If this is included after defining AO_REQUIRE_CAS, then the package makes
+an attempt to emulate AO_compare_and_swap* (single-width) in a way that (at
+least on Linux) should still be async-signal-safe.  As a result, most other
+atomic operations will then be defined using the compare-and-swap
+emulation.  This emulation is slow, since it needs to disable signals.
+And it needs to block in case of contention.  If you care about performance
+on a platform that can't directly provide compare-and-swap, there are
+probably better alternatives.  But this allows easy ports to some such
+platforms (e.g. PA_RISC).  The option is ignored if compare-and-swap
+can be implemented directly.
+
+If atomic_ops.h is included after defining AO_USE_PTHREAD_DEFS, then all
+atomic operations will be emulated with pthread locking.  This is NOT
+async-signal-safe.  And it is slow.  It is intended primarily for debugging
+of the atomic_ops package itself.
+
+Note that the implementation reflects our understanding of real processor
+behavior.  This occasionally diverges from the documented behavior.  (E.g.
+the documented X86 behavior seems to be weak enough that it is impractical
+to use.  Current real implementations appear to be much better behaved.)
+We of course are in no position to guarantee that future processors
+(even HPs) will continue to behave this way, though we hope they will.
+
+This is a work in progress.  Corrections/additions for other platforms are
+greatly appreciated.  It passes rudimentary tests on X86, Itanium, and
+Alpha.
+
+OPERATIONS:
+
+Most operations operate on values of type AO_t, which are unsigned integers
+whose size matches that of pointers on the given architecture.  Exceptions
+are:
+
+- AO_test_and_set operates on AO_TS_t, which is whatever size the hardware
+supports with good performance.  In some cases this is the length of a cache
+line.  In some cases it is a byte.  In many cases it is equivalent to AO_t.
+
+- A few operations are implemented on smaller or larger size integers.
+Such operations are indicated by the appropriate prefix:
+
+AO_char_... Operates on unsigned char values.
+AO_short_... Operates on unsigned short values.
+AO_int_... Operates on unsigned int values.
+
+(Currently a very limited selection of these is implemented.  We're
+working on it.)
+
+The defined operations are all of the form AO_[<size>_]<op><barrier>(<args>).
+
+The <op> component specifies an atomic memory operation.  It may be
+one of the following, where the corresponding argument and result types
+are also specified:
+
+void nop()
+        No atomic operation.  The barrier may still be useful.
+AO_t load(const volatile AO_t * addr)
+        Atomic load of *addr.
+void store(volatile AO_t * addr, AO_t new_val)
+        Atomically store new_val to *addr.
+AO_t fetch_and_add(volatile AO_t *addr, AO_t incr)
+        Atomically add incr to *addr, and return the original value of *addr.
+AO_t fetch_and_add1(volatile AO_t *addr)
+        Equivalent to AO_fetch_and_add(addr, 1).
+AO_t fetch_and_sub1(volatile AO_t *addr)
+        Equivalent to AO_fetch_and_add(addr, (AO_t)(-1)).
+void and(volatile AO_t *addr, AO_t value)
+        Atomically 'and' value into *addr.
+void or(volatile AO_t *addr, AO_t value)
+        Atomically 'or' value into *addr.
+void xor(volatile AO_t *addr, AO_t value)
+        Atomically 'xor' value into *addr.
+int compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val)
+        Atomically compare *addr to old_val, and replace *addr by new_val
+        if the first comparison succeeds.  Returns nonzero if the comparison
+        succeeded and *addr was updated.
+AO_t fetch_compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val)
+        Atomically compare *addr to old_val, and replace *addr by new_val
+        if the first comparison succeeds; returns the original value of *addr.
+AO_TS_VAL_t test_and_set(volatile AO_TS_t * addr)
+        Atomically read the binary value at *addr, and set it.  AO_TS_VAL_t
+        is an enumeration type which includes two values AO_TS_SET and
+        AO_TS_CLEAR.  An AO_TS_t location is capable of holding an
+        AO_TS_VAL_t, but may be much larger, as dictated by hardware
+        constraints.  Test_and_set logically sets the value to AO_TS_SET.
+        It may be reset to AO_TS_CLEAR with the AO_CLEAR(AO_TS_t *) macro.
+        AO_TS_t locations should be initialized to AO_TS_INITIALIZER.
+        The values of AO_TS_SET and AO_TS_CLEAR are hardware dependent.
+        (On PA-RISC, AO_TS_SET is zero!)
+
+Test_and_set is a more limited version of compare_and_swap.  Its only
+advantage is that it is more easily implementable on some hardware.  It
+should thus be used if only binary test-and-set functionality is needed.
+
+If available, we also provide compare_and_swap operations that operate
+on wider values.  Since standard data types for double width values
+may not be available, these explicitly take pairs of arguments for the
+new and/or old value.  Unfortunately, there are two common variants,
+neither of which can easily and efficiently emulate the other.
+The first performs a comparison against the entire value being replaced,
+where the second replaces a double-width replacement, but performs
+a single-width comparison:
+
+int compare_double_and_swap_double(volatile AO_double_t * addr,
+                                   AO_t old_val1, AO_t old_val2,
+                                   AO_t new_val1, AO_t new_val2);
+
+int compare_and_swap_double(volatile AO_double_t * addr,
+                            AO_t old_val1,
+                            AO_t new_val1, AO_t new_val2);
+
+where AO_double_t is a structure containing AO_val1 and AO_val2 fields,
+both of type AO_t.  For compare_and_swap_double, we compare against
+the val1 field.  AO_double_t exists only if AO_HAVE_double_t
+is defined.
+
+Please note that AO_double_t (and AO_stack_t) variables should be properly
+aligned (8-byte alignment on 32-bit targets, 16-byte alignment on 64-bit ones)
+otherwise the behavior of a double-wide atomic primitive might be undefined
+(or an assertion violation might occur) if such a misaligned variable is
+passed (as a reference) to the primitive.  Global and static variables should
+already have proper alignment automatically but automatic variables (i.e.
+located on the stack) might be misaligned because the stack might be
+word-aligned (e.g. 4-byte stack alignment is the default one for x86).
+Luckily, stack-allocated AO variables is a rare case in practice.
+
+ORDERING CONSTRAINTS:
+
+Each operation name also includes a suffix that specifies the associated
+ordering semantics.  The ordering constraint limits reordering of this
+operation with respect to other atomic operations and ordinary memory
+references.  The current implementation assumes that all memory references
+are to ordinary cacheable memory; the ordering guarantee is with respect
+to other threads or processes, not I/O devices.  (Whether or not this
+distinction is important is platform-dependent.)
+
+Ordering suffixes are one of the following:
+
+<none>: No memory barrier.  A plain AO_nop() really does nothing.
+_release: Earlier operations must become visible to other threads
+          before the atomic operation.
+_acquire: Later operations must become visible after this operation.
+_read: Subsequent reads must become visible after reads included in
+       the atomic operation or preceding it.  Rarely useful for clients?
+_write: Earlier writes become visible before writes during or after
+        the atomic operation.  Rarely useful for clients?
+_full: The associated operation is ordered with respect to both earlier and
+       later memory ops.  If the associated operation is nop, then this orders
+       all earlier memory operations with respect to subsequent ones.
+       AO_store_full or AO_nop_full are the normal ways to force a store
+       to be ordered with respect to a later load.
+_release_write: Ordered with respect to earlier writes.  This is
+                normally implemented as either a _write or _release
+                barrier.
+_acquire_read: Ordered with respect to later reads. This is
+                normally implemented as either a _read or _acquire barrier.
+_dd_acquire_read: Ordered with respect to later reads that are data
+               dependent on this one.  This is needed on
+               a pointer read, which is later dereferenced to read a
+               second value, with the expectation that the second
+               read is ordered after the first one.  On most architectures,
+               this is equivalent to no barrier.  (This is very
+               hard to define precisely.  It should probably be avoided.
+               A major problem is that optimizers tend to try to
+               eliminate dependencies from the generated code, since
+               dependencies force the hardware to execute the code
+               serially.)
+
+We assume that if a store is data-dependent on a previous load, then
+the two are always implicitly ordered.
+
+It is possible to test whether AO_<op><barrier> is available on the
+current platform by checking whether AO_HAVE_<op>_<barrier> is defined
+as a macro.
+
+Note that we generally don't implement operations that are either
+meaningless (e.g. AO_nop_acquire, AO_nop_release) or which appear to
+have no clear use (e.g. AO_load_release, AO_store_acquire, AO_load_write,
+AO_store_read).  On some platforms (e.g. PA-RISC) many operations
+will remain undefined unless AO_REQUIRE_CAS is defined before including
+the package.
+
+When typed in the package build directory, the following command
+will print operations that are unimplemented on the platform:
+
+make test_atomic; ./test_atomic
+
+The following command generates a file "list_atomic.i" containing the
+macro expansions of all implemented operations on the platform:
+
+make list_atomic.i
+
+Known issues include:
+
+We should be more precise in defining the semantics of the ordering
+constraints, and if and how we can guarantee sequential consistency.
+
+Dd_acquire_read is very hard or impossible to define in a way that cannot
+be invalidated by reasonably standard compiler transformations.
+
+There is probably no good reason to provide operations on standard
+integer types, since those may have the wrong alignment constraints.
+
+
+Example:
+
+If you want to initialize an object, and then "publish" a pointer to it
+in a global location p, such that other threads reading the new value of
+p are guaranteed to see an initialized object, it suffices to use
+AO_release_write(p, ...) to write the pointer to the object, and to
+retrieve it in other threads with AO_acquire_read(p).
+
+Platform notes:
+
+All X86: We quietly assume 486 or better.
+
+Gcc on x86:
+Define AO_USE_PENTIUM4_INSTRS to use the Pentium 4 mfence instruction.
+Currently this is appears to be of marginal benefit.

+The libatomic_ops_gpl includes a simple almost-lock-free malloc implementation.
+
+This is intended as a safe way to allocate memory from a signal handler,
+or to allocate memory in the context of a library that does not know what
+thread library it will be used with.  In either case locking is impossible.
+
+Note that the operations are only guaranteed to be 1-lock-free, i.e. a
+single blocked thread will not prevent progress, but multiple blocked
+threads may.  To safely use these operations in a signal handler,
+the handler should be non-reentrant, i.e. it should not be interruptable
+by another handler using these operations.  Furthermore use outside
+of signal handlers in a multithreaded application should be protected
+by a lock, so that at most one invocation may be interrupted by a signal.
+The header will define the macro "AO_MALLOC_IS_LOCK_FREE" on platforms
+on which malloc is completely lock-free, and hence these restrictions
+do not apply.
+
+In the presence of threads, but absence of contention, the time performance
+of this package should be as good, or slightly better than, most system
+malloc implementations.  Its space performance
+is theoretically optimal (to within a constant factor), but probably
+quite poor in practice.  In particular, no attempt is made to
+coalesce free small memory blocks.  Something like Doug Lea's malloc is
+likely to use significantly less memory for complex applications.
+
+Performance on platforms without an efficient compare-and-swap implementation
+will be poor.
+
+This package was not designed for processor-scalability in the face of
+high allocation rates.  If all threads happen to allocate different-sized
+objects, you might get lucky.  Otherwise expect contention and false-sharing
+problems.  If this is an issue, something like Maged Michael's algorithm
+(PLDI 2004) would be technically a far better choice.  If you are concerned
+only with scalability, and not signal-safety, you might also consider
+using Hoard instead.  We have seen a factor of 3 to 4 slowdown from the
+standard glibc malloc implementation with contention, even when the
+performance without contention was faster.  (To make the implementation
+more scalable, one would need to replicate at least the free list headers,
+so that concurrent access is possible without cache conflicts.)
+
+Unfortunately there is no portable async-signal-safe way to obtain large
+chunks of memory from the OS.  Based on reading of the source code,
+mmap-based allocation appears safe under Linux, and probably BSD variants.
+It is probably unsafe for operating systems built on Mach, such as
+Apple's Darwin.  Without use of mmap, the allocator is
+limited to a fixed size, statically preallocated heap (2MB by default),
+and will fail to allocate objects above a certain size (just under 64K
+by default).  Use of mmap to circumvent these limitations requires an
+explicit call.
+
+The entire interface to the AO_malloc package currently consists of:
+
+#include <atomic_ops_malloc.h> /* includes atomic_ops.h */
+
+void *AO_malloc(size_t sz);
+void AO_free(void *p);
+void AO_malloc_enable_mmap(void);

+Note that the AO_stack implementation is licensed under the GPL,
+unlike the lower level routines.
+
+The header file atomic_ops_stack.h defines a linked stack abstraction.
+Stacks may be accessed by multiple concurrent threads.  The implementation
+is 1-lock-free, i.e. it will continue to make progress if at most one
+thread becomes inactive while operating on the data structure.
+
+(The implementation can be built to be N-lock-free for any given N.  But that
+seems to rarely be useful, especially since larger N involve some slowdown.)
+
+This makes it safe to access these data structures from non-reentrant
+signal handlers, provided at most one non-signal-handler thread is
+accessing the data structure at once.  This latter condition can be
+ensured by acquiring an ordinary lock around the non-handler accesses
+to the data structure.
+
+For details see:
+
+Hans-J. Boehm, "An Almost Non-Blocking Stack", PODC 2004,
+http://portal.acm.org/citation.cfm?doid=1011767.1011774
+(This is not exactly the implementation described there, since the
+interface was cleaned up in the interim.  But it should perform
+very similarly.)
+
+We use a fully lock-free implementation when the underlying hardware
+makes that less expensive, i.e. when we have a double-wide compare-and-swap
+operation available.  (The fully lock-free implementation uses an AO_t-
+sized version count, and assumes it does not wrap during the time any
+given operation is active.  This seems reasonably safe on 32-bit hardware,
+and very safe on 64-bit hardware.) If a fully lock-free implementation
+is used, the macro AO_STACK_IS_LOCK_FREE will be defined.
+
+The implementation is interesting only because it allows reuse of
+existing nodes.  This is necessary, for example, to implement a memory
+allocator.
+
+Since we want to leave the precise stack node type up to the client,
+we insist only that each stack node contains a link field of type AO_t.
+When a new node is pushed on the stack, the push operation expects to be
+passed the pointer to this link field, which will then be overwritten by
+this link field.  Similarly, the pop operation returns a pointer to the
+link field of the object that previously was on the top of the stack.
+
+The cleanest way to use these routines is probably to define the stack node
+type with an initial AO_t link field, so that the conversion between the
+link-field pointer and the stack element pointer is just a compile-time
+cast.  But other possibilities exist.  (This would be cleaner in C++ with
+templates.)
+
+A stack is represented by an AO_stack_t structure.  (This is normally
+2 or 3 times the size of a pointer.)  It may be statically initialized
+by setting it to AO_STACK_INITIALIZER, or dynamically initialized to
+an empty stack with AO_stack_init.  There are only three operations for
+accessing stacks:
+
+void AO_stack_init(AO_stack_t *list);
+void AO_stack_push_release(AO_stack_t *list, AO_t *new_element);
+AO_t * AO_stack_pop_acquire(volatile AO_stack_t *list);
+
+We require that the objects pushed as list elements remain addressable
+as long as any push or pop operation are in progress.  (It is OK for an object
+to be "pop"ped off a stack and "deallocated" with a concurrent "pop" on
+the same stack still in progress, but only if "deallocation" leaves the
+object addressable.  The second "pop" may still read the object, but
+the value it reads will not matter.)
+
+We require that the headers (AO_stack objects) remain allocated and
+valid as long as any operations on them are still in-flight.
+
+We also provide macros AO_REAL_HEAD_PTR that converts an AO_stack_t
+to a pointer to the link field in the next element, and AO_REAL_NEXT_PTR
+that converts a link field to a real, dereferencable, pointer to the link field
+in the next element.  This is intended only for debugging, or to traverse
+the list after modification has ceased.  There is otherwise no guarantee that
+walking a stack using this macro will produce any kind of consistent
+picture of the data structure.

+Most of the atomic_ops functionality is available under Win32 with
+the Microsoft tools, but the build process currently is considerably more
+primitive than on Linux/Unix platforms.
+
+To build:
+
+1) Go to the src directory in the distribution.
+2) Make sure the Microsoft command-line tools (e.g. nmake) are available.
+3) Run "nmake -f Makefile.msft".  This should run some tests, which
+may print warnings about the types of the "Interlocked" functions.
+I haven't been able to make all versions of VC++ happy.  If you know
+how to, please send a patch.
+4) To compile applications, you will need to retain or copy the following
+pieces from the resulting src directory contents:
+        "atomic_ops.h" - Header file defining low-level primitives.  This
+                         includes files from:
+        "atomic_ops"- Subdirectory containing implementation header files.
+        "atomic_ops_stack.h" - Header file describing almost lock-free stack.
+        "atomic_ops_malloc.h" - Header file describing almost lock-free malloc.
+        "libatomic_ops_gpl.lib" - Library containing implementation of the
+                        above two (plus AO_pause() defined in atomic_ops.c).
+                        The atomic_ops.h implementation is entirely in the
+                        header files in Win32.
+
+If the client defines AO_ASSUME_VISTA (before include atomic_ops.h), it should
+make double_compare_and_swap_full available.
+
+Note that the library is covered by the GNU General Public License, while
+the top 2 of these pieces allow use in proprietary code.

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##

+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.

+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to

+# expanded when the contents are evaled.

+# override it after sourcing this library to reflect the full set of

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.
