You seem to have stumbled upon an untested compiler/runtime combination (clang +
runtime from GCC 4.4.5).

This seems to be a bug ... the "typedef unsigned char BOOL;" in 
ObjectiveC2/runtime.h
is protected by #ifndef __objc_INCLUDE_GNU, but since objc/objc.h is included 
*after*
ObjectiveC2/runtime.h, __objc_INCLUDE_GNU is not #defined yet, and the 
protection does
not work.

Thanks
