Hi Reimar,

the thing is that at least for me the problem doesn't originate from 
using distcc. I haven't even installed distcc on the machine where this 

Also it tells me (mplayer -v):
Compiled for x86 CPU with extensions: MMX MMX2 3DNow 3DNowEx SSE SSE2

I was not compiling this with SSE and SSE2! I know the tbird doesn't 
support these instruction sets. I only have enabled both mmx and 3dnow 
instr sets in my USE flags.

If I don't enabled custom-cflags on this box the makefile seems to pass 
these optimization options to gcc:
-O4 -march=i486 -mtune=i686 -pipe -ffast-math -fomit-frame-pointer

Resulting in the use of SSE instr.

With custom-cflags:
-O2 -march=athlon-tbird -pipe -fomit-frame-pointer
Producing a working build.

Is this the mplayer Makefile or the gentoo ebuild?
