A while ago, I discovered the ObjFW runtime for Objective-C, which is a pretty neat one and does a lot of things - and, is very tiny. But it made me ask lately, which runtimes are available on which targets - and how can one best find out? I'd like to use a small script in my configuration to test if I could use ObjFW on the current platform, with the current clang or gcc installation.
So is there a way to list the available Objective-C runtimes on either GCC or Clang?
