Good question. It seems unfriendly. It looks like you're just about guaranteed to get a warning if you include any system header before you include Python.h.
So either we have to dance around that or we have to give up the idea that postgres.h must come first. It wouldn't be the first time we've had to do that sort of dance.
The reason we get warnings about these and not about many other things it defines (such as the HAVE_foo macros) is that these are set to values different from those encountered in the previously included headers.
