+ *#* Revision 1.36  2004/12/08 08:55:54  bernie
+ *#* Rename sigset_t to sigmask_t and time_t to mtime_t, to avoid conflicts with POSIX definitions.
+ *#*
+ *#* Revision 1.35  2004/12/08 07:35:51  bernie
+ *#* Typo in macro name.

+ *#* Revision 1.34  2004/11/28 23:21:33  bernie
+ *#* Use mtime_t instead of overloading ANSI time_t with new semantics.
+ *#*
+ *#* Revision 1.33  2004/11/16 23:09:40  bernie
+ *#* size_t: Add 64bit definitions; time_t: Add 16bit hack for tiny CPUs.

  *#* Revision 1.32  2004/11/16 22:42:44  bernie
  *#* Doxygen fixes.
