That doesn't sound too bad :)

I'm currently fighting with cross-compiling (for i386 and ppc) on 10.6
and usually setting CC="gcc -arch ppc" is a much safer recipe that
making sure that the software consistently switches to obeying CFLAGS.

I wonder if we should introduce a variant of the compiler to do just that :)

Thanks in advance :)
