Thanks!

As gcc should be able to utilize MMX, SSE, SSE2 and 3dnow with inline
assembly now, it would be nice if someone would try to use it instead of
using a 3rd party assembler. The actual implementation of how we add the
assembly parts into lame is a bad hack, and I would like to get rid of
it.

If you don't know how to use autoconf/automake in the first place, you
don't want to try to add non-libtool generated files into the mix from
scratch. Thrust me, I've done the integration of the actual x86-asm bits
into the configure system. If you don't want to go the gcc-inline
assembly route feel free to have a look at libmp3lame/i386/Makefile.am,
everything else gets generated by autoconf/automake (if you add an amd64
subdir you have to add it to configure.in and to
libmp3lame/Makefile.am).
Bye,
Alexander.
