[FFmpeg-devel] [PATCH 2/4] Define __EXTENSIONS__ to enable struct ip_mreq access on OpenSolaris.

Like for recent GLIBC versions, even OpenSolaris hides the ip_mreq
structure by default on C99/POSIX.1-2001 code, to access it, the
__EXTENSIONS__ macro has to be defined.

Define it so that udp.c builds properly on OpenSolaris.
