[Ffmpeg-devel] Latest SVN FFmpeg doesn't compile using GCC 2.96 under Redhat 7.3

[Pixelib Team]

First of all, FFmpeg 0.4.9 pre1 has ever been compiled using GCC
2.96successfully at Redhat
7.3 even though there were lots of warning messages.

Recently, I have been trying to compile the latest svn version of FFmpeg
couples of weeks, unfortunately, after showing lots of warning messages, the
compile process did hang there and nothing happened again.

any idea ?

Steve
