commit 3b566046c3e8cb252f4c0ab7b6041fef5098f1a5
Author: Siddhesh Poyarekar <siddhesh@redhat.com>
Date: Mon Dec 29 17:39:30 2014 +0530
Add _POSIX namespace SYSCONF macros to posix-conf-vars.list
This fixes the remaining -Wundef warnings. Tested on x86_64.
* posix/posix-conf-vars.list: Add _POSIX sysconf namespace.
* sysdeps/posix/sysconf.c: Include posix-conf-vars.h.
(__sysconf): Use CONF_IS_* macros.
