Let me re-phrase what Shy said.
Mppenc's assembly code (fft4gasm.nas) contains 3DNow-optimized versions of some of functions, it's deprecated and does not appear to give significant improvement on current CPUs, at least with Microsoft compilers. Fft4gasm.nas will be most likely dropped from sourcecode package in next release.
Additionally, source code needs to be modified for functions from assembly module to be actually called. If you compile current source even with assembly module included, assembly functions are never called, unless you alter relevant line of fft4g.c.
