All the above are harmless.

This one is of course not harmless, but since the error is in an Apple supplied header file, and I don't have the gcc version at hand, I will not be able to fix the issue quickly. It seems that the FL/mac.H header file overrides something that CF later needs. 

Please try to add this line:
#include <Carbon/Carbon.h>

as the first line in FL.cxx and let me know if the error goes away.

Harmless

Haha. Well, on earlier versions of OS X, TransformProcessType actually *is* NULL. ;-) . Anyway, harmless.
