Nope, I'm using Linux.  I'd like to see these definitions
provided regardless of OS, though.

I suppose my next move is to post a gcc patch to
the linux-ppc mailing list, and see if I can get people there 
interested in advocating it.  The patch would probably be to
rs6000/sysv4.h, and would add -D__PPC750__ etc to CPP_CPU_SPEC,
unless I'm confused.
