My configuration command line was
/nfs/scratch/Developer/ffmpeg-git-src/configure --prefix=/Developer/ppc 
--enable-swscale --enable-avfilter --enable-libmp3lame --enable-libvorbis 
--enable-libopus --enable-libtheora --enable-libschroedinger 
--enable-libopenjpeg --enable-libmodplug --enable-libvpx --enable-libspeex 
--enable-shared --enable-pthreads --enable-gpl --enable-version3 
--enable-libopencore-amrnb --enable-libopencore-amrwb --enable-postproc 
--enable-libx264 --enable-libxvid --enable-runtime-cpudetect 
--extra-cflags=-I/opt/local/include 
--extra-ldflags='-headerpad_max_install_names -L/opt/local/lib'

and I've attached gas-preprocessor.pl that I used to enable ffmpeg assembly 
compilation for osx PPC.  In the past I compiled successfully without 
gas-preprocessor, but that means I didn't get any assembly optimization in my 
PPC build.

I don't see any recent changes in git log.  The get_got macro was added more 
than a year ago.  Am I the first one to try to build this configuration?  
Unfortunately I am not qualified to fix assembly code myself, so I'll need some 
help.

Thank you,
     Pavel
