Basically use 'cc -arch i386 -arch ppc -isysroot /Developer/SDKs/ 10.4u.sdk' as the compiler and hope that configure doesn't check for endianness. (There may be spelling errors in that command-line, I haven't checked my build script).

That shouldn't be a problem until someone starts playing with dlopen flags, and that can't happen at the moment because dynload_next doesn't look at those :-). > > b) If not, then I guess it's just a waste-of-memory issue, which > probably isn't a big deal, but seems wasteful.

I don't know about the latter but the former shouldn't be a problem, you'll just have to make sure that the right linker arguments are used.
