A few warnings:

sbc/sbc.c:558:34: warning: always_inline function might not be inlinable [-Wattributes]
sbc/sbc.c:163:31: warning: always_inline function might not be inlinable [-Wattributes]

and an error

sbc/sbc_primitives_mmx.c: In function 'sbc_calc_scalefactors_mmx':
sbc/sbc_primitives_mmx.c:294:4: warning: asm operand 2 probably doesn't match constraints [enabled by default]

Full build log:
http://koji.fedoraproject.org/koji/getfile?taskID=3657376&name=build.log
Using gcc 4.7.0 as mentioned in root log:
http://koji.fedoraproject.org/koji/getfile?taskID=3657376&name=root.log

The same build works correctly with gcc 4.6.1 on Fedora 16.

Any ideas?
