The idea is that they as portable as possible, and they are generated
by directly testing code - generating a type and prodding sizeof it.
The hope is that even a really broken setup can't lie about those sort
of things :)

Yes, but the reason we need to do these hacks is precisely because the
standard is badly implemented. I think this these types are defined on
Linux/glibc, rather than in standard C, but may well be wrong.

As for the rest of the things, I'm not really sure - I guess only Tom
will know exactly why this was done the way it was - and might relate
to Autoconf, and hence is a good reason to change it :)
