That's it __ppc__ and __i386__ works. ( And I guess __VEC__ and

In general, we recommend that you use the #defines closest to the
kind of change you're #defining in or out. In other words, __VEC__
and __SSE__ would be preferred here.
Also, for what it's worth, gcc on Mac OS X defaults to -msse2 when
building for Intel, so you don't need to check for __SSE__ unless
you're using that as a way to avoid building the code in question for
PowerPC.
