Summary: Warnings in Python.h with gcc 4.0.0
Initial Comment:
(this happens for every file that includes Python.h)
In file included from ../Include/Python.h:55,
from ../Objects/intobject.c:4:
../Include/pyport.h:396: warning: 'struct winsize' declared inside
parameter list
../Include/pyport.h:397: warning: 'struct winsize' declared inside
parameter list
The source lines look like this:
extern int openpty(int *, int *, char *, struct termios *, struct
winsize *);
extern int forkpty(int *, char *, struct termios *, struct winsize *);

The warning almost certainly means that there's no
declaration of struct winsize in scope when these externs are
declared. That's bad, because C doesn't guarantee that all
pointers are the same size (although they are on all Python
platforms I'm aware of).
Some quality time with Google suggested that other projects
wormed around this by #include'ing <termio.h> instead of
<termios.h>, because the former but not the latter #include's
<sys/ioctl.h> where the winsize struct was defined. Beats
me -- ain't a Windows problem <wink>.

Beats me, it's probably just "bad style".
It's a problem because it shows up a lot in the output, so we should at
least figure out how to disable this warning so that it doesn't become
annoying.

Why is this a problem? Is it not valid C or something?
