Author: jilles Date: Thu Mar 3 22:34:13 2011 New Revision: 219256 URL: http://svn.freebsd.org/changeset/base/219256 Log: 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.
