Sorry, I did not mean those exact defines, but the applicable ones.  The
why it is done in i386/i386.h and alpha/alpha.h would work for rs6000.h
maybe.  I don't know the exact -D's to use, but I'm sure you guys do.


#define CPP_CPU_SPEC \
"%{!mcpu*: \
  %{mpower: %{!mpower2: -D_ARCH_PWR -D__power__}} \
  %{mpower2: -D_ARCH_PWR2 -D__power__ -D__power2__} \
  %{mpowerpc*: -D_ARCH_PPC -D__powerpc__} \
..snip..
%{mcpu=603: -D_ARCH_PPC -D__powerpc__ -D__ppc__ -D__ppc603__ -Acpu=powerpc -Amachine=powerpc} \
..snip..
%{mcpu=740: -D_ARCH_PPC -D__powerpc__ -D__ppc__ -D__ppc740__ -Acpu=powerpc -Acpu=powerpc -Amachine=powerpc} \
..etc..
