    - 64bitfs   (should be on if libc switches to a 64-bit system.

All three tested systems (PPC,Alpha,2x i386) gave the same POSIX limits,
and all three 32-bit systems returned completely identical types too
(everything 32-bit except dev_t, which is assumed to be a result of devfs
introduction)

   $Log$
   Revision 1.11  2004-09-09 20:29:06  jonas
     * fixed definition of pthread_mutex_t for non-linux targets (and for
       linux as well, actually).
     * base libpthread definitions are now in ptypes.inc, included in unixtype
       They sometimes have an extra underscore in front of their name, in
       case they were also exported by the packages/base/pthreads unit, so
       they can keep their original name there
     * cthreadds unit now imports systuils, because it uses exceptions (it
       already did so before as well)
     * fixed many linux definitions of libpthread functions in pthrlinux.inc
       (integer -> cint etc)
     + added culonglong type to ctype.inc

   Revision 1.10  2004/05/02 01:00:07  peter
     * statfs fixed

   Revision 1.9  2004/04/26 16:53:19  peter
     * use cpu64

   Revision 1.8  2004/03/04 22:15:16  marco
    * UnixType changes. Please report problems to me.

   Revision 1.7  2004/01/11 09:56:20  jonas
     * moved tstatfs from systypes.inc to ptypes.inc to fix make cycle with
       -dFPC_USE_LIBC (systypes.inc is now completely commented out)

   Revision 1.6  2003/12/30 12:46:40  marco
    * ptime_t

   Revision 1.5  2003/09/27 13:45:58  peter
     * fpnanosleep exported in baseunix
     * fpnanosleep has pointer arguments to be C compliant

   Revision 1.4  2003/09/14 20:15:01  marco
    * Unix reform stage two. Remove all calls from Unix that exist in Baseunix.

   Revision 1.3  2002/12/18 16:43:26  marco
    * new unix rtl, linux part.....

   Revision 1.2  2002/11/12 14:28:40  marco
    * some updates

   Revision 1.1  2002/10/29 16:47:17  marco
    * Linux versions
