So an Apple engineer spent time adding support for more 'liberal', non-Apple-based Objective-C runtimes? Wow! That seems unusual of Apple, but very cool. EDIT

So an Apple engineer spent time adding support for more 'liberal', non-Apple-based Objective-C runtimes? Wow! That seems unusual of Apple, but very cool. EDIT - Looking at the clang source, it looks like GNUstep and and ObjFW (with the exception of old GCC) are the only alternative Objective-C runtimes currently supported by clang: http://clang.llvm.org/doxygen/ObjCRuntime_8h_source.html http://clang.llvm.org/doxygen/ObjCRuntime_8h_source.html

What other alternative runtimes even exist?

Unusual? It'd seem beneficial to Apple in several ways, in that they have multiple ABIs (see the code there!), and in that it keeps other Obj-C users interested in Clang (which means more outside work on the Obj-C frontend).
