[mythtv-users] Official Gentoo Ebuild is broken

[Jon Waite]

I a very similar error while compiling libavcodec a couple of days back -
solution for me was to change '-march=pentium4' to '-mcpu=pentium4' in the
gcc options. There should be a token for this in the Makefile or script
somewhere that you can hack. So I'd try (in your case) '-mcpu=athlon-xp' or
'-march=i386' and see if that gets you past it.

Of course this could be something completely different (I'm am not a GCC
expert by any means), but it worked for me.
