Are you sure you have the latest MPlayer CVS, and not some other CVS?
"fourc" was removed from line 70 of ad_ffmpeg.c in MPlayer's CVS, way
back in March of this year:

Adding "-m3dnow" to your build options does you no good, by the way.
What that does is make visible certain functions in lib_gcc, none of
which are used by MPlayer in any case. MPlayer's 3DNow inline assy
optimizations are enabled by setting TARGET_3DNOW=yes in "config.mak",
which should happen automatically.
