I've been looking into the problem with warnings today.

At IronPort we build frozen, statically-linked binaries, so we're still
using Modules/Setup.local to build our extensions.

We use '-Wall' in everything we build, and of course we can't relax that
just to handle pyrex output.  However, the following trick seems to
work, with gcc, on a single module.

1) Add 'W' to the list of 'cppargs' in Modules/makesetup (line 161):
-                       -[IDUCfF]*)     cpps="$cpps $arg";;
+                       -[IDUCfFW]*)    cpps="$cpps $arg";;

2) Add '-Wno-unused' to the line in Setup:

mymod -Wno-unused mymod.c

This is still leaving 'uninitialized' warnings, but I'm sure that can be
dealt with the same way...
