__FUNCTION__ is aliased to __func__ and has been for some time. Please
DO NOT use __FUNCTION__. The only reason to use this is on _old_
versions of GCC. __func__ is standardized and has been since the early
drafts of C99.

Ew. That's a broken appearing implementation of old-style c
declarations. This would be somewhat useful when digging through
/usr/include, however, since no sane programmers (/me dons flame
retardent undies) write their declarations this way it isn't possible
without reformatting all of your system headers.
If you do this in your own code I'd just recommend getting a decent IDE
to program in: Xcode, SlickEdit, even emacs are more than capable of
returning you function declarations based on simple searches across the
whole project without necessitating the adoption of uncommon
programming styles to ease grepping.
