From e650bdac9cd67f886b27bea013f97633ffaee3bb Mon Sep 17 00:00:00 2001 From: jilles Date: Thu, 3 Mar 2011 22:34:13 +0000 Subject: [PATCH] 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.
