Just an FYI for Chris and anyone else interested, 
__CFStringMakeConstantString is the macro expansion of the C macro 
CFSTR.  There are a few places in the Carbon APIs where Apple has used 
C macros for convenience "functions".  I've had better luck using the 
macro expansions since there are no macros exported by the framework 
libraries.  It's something of a nuisance that Apple's documentation 
generally doesn't tell you that function foo is really a macro.
