Why libmad? Has it been improved for ARM?

We do not support anything older than pre7, and for bugreports you
should use CVS.

?? I don't understand that... But you can set these devices on the

?? --with-madlibdir= should set this.

Why this? If this is necessary you did something wrong I'm quite sure.

--host-cc and you don't need this hacking for codec-cfg. If you were

try -ac mad or --disable-mp3lib for configure.

try -vfm ffmpeg. And double-check that you do not use a gcc
version with known bugs.
