[Python-Dev] warnings in libffi

[Brett Cannon]

gcc 4.0.1 on OS X is spitting out some warnings about libffi:

build/temp.darwin-8.5.0-Power_Macintosh-2.5/libffi/include/ffi.h:191:
warning: function declaration isn't a prototype

All of them are for function parameters of function pointers (``void
(*fn)(void)`` and such) when used in both function prototypes and
function declarations.  Do we fix these ourselves, or do we report
them to the libffi maintainers (or are whom)?
