I did not anticipate people would disagree on the idea of removing
warnings, so I guess thare are two questions:
 - why / why not removing bogus warnings
 - if removing is considered OK, what's the best method: with the
compiler-specific method, it could be done automatically and safely
with some regex.

Yes, at least on some platforms: this is addressed by using the
inttypes.h header, proof of concept here:

http://projects.scipy.org/scipy/numpy/ticket/847

But it would need a configuration stage to test we have the required
formats in inttypes (the patch relies on how configuration is done in
the python header, which I don't like and is not really robust).
