It's not only a question of compilers – you also need SDKs!

If you want to create new binaries which also run on Tiger you need the MacOSX10.4u.sdk *and* GCC 4.0.1.
If you want to create new binaries which also run on Leopard you need the MacOSX10.5.sdk and you can use GCC 4.2.1.
If you want to create new binaries which also run on Snow Leopard you need the MacOSX10.6.sdk and you can use GCC 4.2.1 or LLVM GCC 4.2.

The Tiger and Leopard SDKs are provided by Xcode 3.1...3.2.6 (the latter also provides Snow Leopard), the Xcode 4.x versions provide only Snow Leopard.

There are two major products that come out of Berkeley: LSD and UNIX. We don't believe this to be a coincidence.
