This won't be easy with GCC. Apple patched a lot to make that happen. Have a
look at Clang instead, which works just fine on Haiku. Clang would be a better
replacement for GCC2 than GCC4 anyway, IMHO, which is why I'm working in
getting Haiku to work when compiled with Clang. The main problems left are in
the kernel space - and my limited time.

I think FatELF should be fully working before we try to add a compatibility
layer for multiarch, don't you think? ;) And even then, I'm not sure how
necessary that will be. And I guess such a compatibility layer will be a huge
pain: After all, it also needs to suppor gcc2 and gcc4.

Nice! I'm looking forward to it, it will really make the GCC2/GCC4 mess easier
