The exact purpose of the line I'm changing here is to detect 32 bit compilation
on 64 bit systems. Since I'm not aware how to set $CFLAGS from the configure
line, I tried ./configure --cc='gcc -m32' (also works with icc 11.0), but needed
attached patch to successfully convince configure that I _really_ want to
compile a 32 bit binary (that is required to play WMA9 files).

Please explain how to fix this differently (or if I'm wrong and it is still
possible to set $CFLAGS) if you don't want me to commit, thank you, Carl Eugen
