[Libav-user] Unable to compile i386 compatible ffmpeg dylibs on Mac OS X

[Simon Daniels]

Hi Carl,

1. ./configure --cc="gcc -m32" --disable-decoder=h264,svq3
--disable-parser=h264 completed just fine without any errors on 0.8.7.

2. I ran ./configure --cc="gcc-m32" on the current git head and got
the same error as before.

3. Ran last gcc command with O1 and O2 and got same error on current
git head (with -fno-omit-frame-pointer at the end).

4. Repeated #2 and #3 with clang on current git head and got the same errors

Thanks!
