- *
- * $Revision: 1.2 $
- *
- * limits.h - POSIX compatible defnitions for some of <limits.h>
- *
- * DESCRIPTION
- *
- * We need to include <limits.h> if this system is being compiled with an
- * ANSI standard C compiler, or if we are running on a POSIX confomrming
- * system. If the manifest constant _POSIX_SOURCE is not defined when
- * <limits.h> is included, then none of the POSIX constants are defined
- * and we need to define them here. It's a bit wierd, but it works.
- *
- * These values where taken from the IEEE P1003.1 standard, draft 12.
- * All of the values below are the MINIMUM values allowed by the standard.
- * Not all values are used by the PAX program, but they are included for
- * completeness, and for support of future enhancements. Please see
- * section 2.9 of the draft standard for more information on the following
- * constants.
