The FATE Server is paying dividends. It seems that the latest SVN builds 
of gcc can not build FFmpeg.


The error is:

make[1]: *** [mpegvideo_enc.o] Error 1

This is on PowerPC with both SVN 131978 and 131996. Unfortunately, I had 
not updated in a few weeks so I didn't catch exactly where the break 
crept in. I have not had time to build current SVN for other platforms.

Where's the best place to report these problems? I should probably 
bookmark it. :)
