Subject: [PATCH] window-x11: Fix _XOPEN_SOURCE usage for gethostname on
 FreeBSD

On FreeBSD, gethostname is guarded by '__POSIX_VISIBLE >= 200112', which
requires either '_POSIX_C_SOURCE >= 200112' or '_XOPEN_SOURCE >= 600'.
Defining _XOPEN_SOURCE to 500 does not break the build because of
implicit declaration, but it defeats the purpose of defining the macro.
