* commit '3c370f5abc55739a261534b9f9bdc739cedbbbb9': riff: only warn on a bad INFO chunk code size instead of failing configure: Add separate list for libraries and use where appropriate x86: float_dsp: add SSE version of vector_fmul_scalar() Conflicts: configure libavformat/riff.c libavutil/x86/float_dsp.asm Merged-by: Michael Niedermayer <michaelni@gmx.at>
