[PATCH] Don't define _XOPEN_SOURCE to unbreak compilation on FreeBSD

From: Rocco Rutte <pdmef@gmx.net>
Date: Dec 21, 2006, 10:47 UTC
Message-ID: <11666980484010-git-send-email-pdmef@gmx.net>

FreeBSD 6 requires the __BSD_VISIBLE flag for fchmod(), IPPROTO_IPV6 and more which is only properly set by <sys/cdefs.h> if _POSIX_C_SOURCE isn't present. However, _POSIX_C_SOURCE is defined if _XOPEN_SOURCE is defined and >=500.

As a solution, simply don't define _XOPEN_SOURCE for FreeBSD and continue with its defaults.
