Comment (by kyngchaos):

 Maybe it needs a different bug report, but now I get some symbols not
 found in the tests, when using a recent ffmpeg.

 {{{
 configure:11056: checking for avcodec_init in -lavcodec
 configure:11073: gcc -o conftest -Os    -L/Users/Shared/unix/ffmpeg-
 leo/lib   conftest.c -lavcodec  -lavutil    1>&5
 Undefined symbols:
   "_inflate", referenced from:
       _decode_frame in libavcodec.a(pngdec.o)
   "_inflateEnd", referenced from:
       _decode_frame in libavcodec.a(pngdec.o)
   "_inflateInit_", referenced from:
       _decode_frame in libavcodec.a(pngdec.o)
 ld: symbol(s) not found
 }}}

 If I add -lz to the test, it works.

 I don't know why the exact same test works without -lz when using an older
 ffmpeg build.
