 On OS X, using --enable-indev=jack, the build fails with

 {{{
 CC      libavdevice/jack_audio.o
 /src/ffmpeg/libavdevice/jack_audio.c: In function 'audio_read_packet':
 /src/ffmpeg/libavdevice/jack_audio.c:277: warning: implicit declaration of
 function 'sem_timedwait'
 AR      libavdevice/libavdevice.a
 LD      libavdevice/libavdevice.52.dylib
 Undefined symbols:
   "_sem_timedwait", referenced from:
       _audio_read_packet in jack_audio.o
 ld: symbol(s) not found

 make: *** [libavdevice/libavdevice.52.dylib] Error 1
 }}}

 sem_* is semaphore_* on OS X.
