Those are almost certainly runtimes shipping with GCC, and they're (like GCC itself when it comes to Objective-C) not recommended these days. Active development of the language is done by Apple and others using Clang, and lately David is implementing new language features more quickly than they appear in released versions of GCC.
So if you want to have the state-of-the-art-while-using-free-platforms Objective-C development environment: - GNUstep built from SVN - Clang built from SVN - libobjc2 built from SVN The most troubling component here is Clang, as Clang and LLVM take quite some time and disk space to be built. So you can try skipping that, it should still be fine.
