New Revision: 219726
URL: http://svn.freebsd.org/changeset/base/219726

Log:
  MFC r219256: Fix some _POSIX minimum/maximum values in limits.h:
  * Some values changed in POSIX.1-2001; provide the former value if a program
    requests compliance to an earlier version of POSIX. [1]
  * Add missing _POSIX_CLOCKRES_MIN constant. This is a maximum value but
    otherwise works the same as the minimum values.
  
  PR:		standards/104743
  Submitted by:	bde [1] (not exact #ifdefs, but the values)

Modified:
  stable/8/include/limits.h
