Compiling gst-plugins, a ffmpeg libavcodec component fails even with conservative optimizations ("-march=i686 -O2") on an AMD Duron (Spitfire core). I even manually removed -fPIC from the ebuild (it adds -fPIC to CFLAGS), to no avail. Compiler: GCC 3.2.3-r1 File: "gst-plugins-0.6.3/gst-libs/ext/ffmpeg/ffmpeg/libavcodec/msmpeg4.c" I had a little bit of time to skim over the code, but it wasn't enough to find a way to fix it. The code looks very brittle, and is riddled with little careless mistakes like the non-fatal warnings in the output snippet below. This is a larger problem because it blocks Gnome 2.4.0 from emerging.
