Just noticed this: #-------------------------------------------------
# specify architecture-specific optimizations
#-------------------------------------------------
# uncomment and specify architecture-specific optimizations here
# some examples:
# optimize for I686: ARCHOPTS = -march=pentiumpro
# optimize for Core 2: ARCHOPTS = -march=pentium-m -msse3
# optimize for G4: ARCHOPTS = -mcpu=G4
# note that we leave this commented by default so that you can
# configure this in your environment and never have to think about it GCC has a -march=core2 now (as of 4.2 IIRC), why not use it?

Those comments are from baseline and do not reflect recommended practice for SDLMAME. No -march flags have ever proven to make an unplayably slow game playable but they are proven to cause GCC to start inserting bugs in the generated code. I do not support or accept bug reports from any SDLMAME built with any ARCHOPTS.
(More directly answering your question: baseline is very conservative on GCC updates - it took forever for there to be a MinGW 4.anything build that was halfway stable, and none of the recent builds would output a properly running MAME last time we tested them).

-march=core2 doesn't do anything special, anyway. It's mostly there to make Gentoo users happy.
