Summary: _POSIX_C_SOURCE redfined

Initial Comment:
I recently build and installed a current CVS python. 
When I used it to build some C extension modules, I get
a warning about redefinition of _POSIX_C_SOURCE.  Is
this related to your recent changes?

It looks like stdio.h is included first (and redundantly) in
ExtensionClass.c.  I've never seen the warning before, so
some recent change to python has exposed the problem in
ExtensionClass.

Unlikely. More likely, ExtensionClass.c includes a system
header before including Python.h, which is an error.
