Summary: HP-UX: _ctypes/libffi/src/ia64/ffi/__attribute__/native cc

Initial Comment:
_ctypes/libffi/src/ia64/ffi.c uses __attribute__((...)) twice. Consequently, ffi.c does not compile with the native compiler 
(cc: HP C/aC++ B3910B A.06.12 [Aug 17 2006]).

Fails on Solaris x86 10 U3 / Sun Studio 11 for the same reasons. It's
uncompilable on x86_64 anyway though, as Sun has no 128-bit integer type,
so the __int128_t in x86/ffi64.c will never compile. I haven't tried
building it in 32-bit mode.

I tried that on a HP testdrive machine.  While the _ctypes extension buils
fine with GCC (*), it does indeed not compile with the native C compiler.
But cc not understanding __attribute__ is only the first problem; if it is
removed there are lots of other compilation problems.  Unless someone can
provide a patch, I'll close this as 'won't fix'.

(*) _ctypes_test.so is also built but fails to load as shared library,
because the symbol __divsf3 is not defined.
