What if you try to build a simple 'Hello World' app that #includes
<CoreFoundation/CoreFoundation.h>?  I guess it will also not build. 
Also add something like:

#ifdef __GNUC__
    print (yes);
#else
    print (no);
#endif

to see if __GNUC__ is defined even in a simple app.  Also, which OS? 
Which Xcode?  And which Mac OS SDK are you using?
