I'm already using the GSFastEnumeration macros in -base, and have been for about six months. If they are relying on C99 features that I didn't notice, no one has reported compilation failures in this time. Unlike the enumerator solution, this gives the same performance and thread-safety as fast enumeration. I'm not sure what the problem is. I didn't put them in the public headers location, because emulating a compiler in the preprocessor seems ugly to me, but if they're generally useful then we can move them there. I also have some similar macros that provide a fast-enumeration style macro for iterating over characters in a string, which I should probably add in the same place - there are a few places where we are doing very slow string iteration in -base.
