Looks like there's quite a bit more work to do. Here's another diff  
to handle more things. I think powerpc_darwin_mach_dep.s needs to be  
customized to work in a 64-bit environment too, but I haven't done that.

I've updated the POWERPC machine type to be more discriminatory:  
POWERPC and POWERPC_64. This is better than my previous usage of  
__ppc__ and __ppc64__ which are gcc-specific.

All these changes are untested, unfortunately. :) I've got access to  
a G5 but not one running MacOSX 10.4.
