I see at http://fate.arrozcru.org/cygwin/ that you use gcc 3.4.6,
4.2.4 and 4.4.3.
And binutils 2.20.

Cygwin's gcc-4 is 4.3.4 and binutils are 2.19.51.
I have built my own 4.2.3 and 4.2.4 and they worked fine: my bet is
that 4.3.4 is the culprit.

The build succeeds, but the resulting .exe fails at startup:

$ strace ./ffmpeg
--- Process 3672, exception C0000005 at 774A5785
--- Process 3672, exception C0000005 at 77469EED
