 Hi,

 I have recently tried to build an mplayer snapshot, which pulls ffmpeg
 git. Unfortunately, it is impossible to build it with gcc-4.7 prerelease,
 which Fedora switched to:

 {{{
 ffmpeg/libavcodec/libavcodec.a(ffv1.o): In function `encode_init':
 /builddir/build/BUILD/mplayer-
 export-2012-02-26/ffmpeg/libavcodec/ffv1.c:1041: undefined reference to
 `__builtin_iround'
 collect2: error: ld returned 1 exit status
 make: *** [mplayer] Error 1
 make: *** Waiting for unfinished jobs....

 `__builtin_iround'
 collect2: error: ld returned 1 exit status
 make: *** [mencoder] Error 1
 }}}
 Any ideas on how to fix this? Or is it perhaps a gcc error? Cheers.
