[MPlayer-dev-eng] about log2 replacement

[Chang Chen]

Hi All

 

In r19395 of libavutil/internal.h, alexc added a inline function for
log2.

 

~~log2~~ isn't c99 standard, but it is defined a macro with build flag
-std=gnu99.

 

ffmpeg use -std=c99,  so this works, but mplayer use -std=gnu99, so
build is broen

 

any suggestion for how to fix this issue?

 

Thanks

Chang
