I have a problem trying to compile unload able bundle with clang. According to CoreFoundation reference (1), when writing such bundle, you should the -fno-constant-cfstrings option to prevent issue with dandling CFStringRef pointer.

Actually, clang completely ignore this flag and always define the __CONSTANT_CFSTRINGS__ macro, used by the CoreFoundation header to conditionally generate constant strings.

I attached a patch to not define this macro when -fno-constant-cfstrings is passed to the compiler.
