{
  possible compiler switches (* marks a currently required switch):
  -----------------------------------------------------------------
  USE_RHIDE           generates errors and warning in an format recognized
                      by rhide
  TP                  to compile the compiler with Turbo or Borland Pascal
  GDB*                support of the GNU Debugger
  I386                generate a compiler for the Intel i386+
  M68K                generate a compiler for the M68000
  USEOVERLAY          compiles a TP version which uses overlays
  DEBUG               version with debug code is generated
  EXTDEBUG            some extra debug code is executed
  SUPPORT_MMX         only i386: releases the compiler switch
                      MMX which allows the compiler to generate
                      MMX instructions
  EXTERN_MSG          Don't compile the msgfiles in the compiler, always
                      use external messagefiles, default for TP
  NOAG386INT          no Intel Assembler output
  NOAG386NSM          no NASM output
  NOAG386BIN          leaves out the binary writer, default for TP
  LOGMEMBLOCKS        adds memory manager which logs the size of
                      each allocated memory block, the information
                      is written to memuse.log after compiling
  -----------------------------------------------------------------

  Required switches for a i386 compiler be compiled by Free Pascal Compiler:
  GDB;I386

  Required switches for a i386 compiler be compiled by Turbo Pascal:
  GDB;I386;TP

  Required switches for a 68000 compiler be compiled by Turbo Pascal:
  GDB;M68k;TP

    * some bug fixes (e.g. must_be_valid and procinfo.funcret_is_valid)
    * most things for stored properties fixed

  Revision 1.47  1999/09/02 18:47:45  daniel
    * Could not compile with TP, some arrays moved to heap
    * NOAG386BIN default for TP
    * AG386* files were not compatible with TP, fixed.

  Revision 1.46  1999/08/28 15:34:20  florian
    * bug 519 fixed

  Revision 1.45  1999/08/04 00:23:18  florian
