I would be all for it.

While we're at it...

How much code would we *really* break if we moved long to 64 bit, and
eventually obsolesced long long?  IMHO, everything in C should pass
-pedantic -Wall.  (It's fine with me if it's system specific, especially
in the kernel, but I think a bit of pedantry could help.)

This would also help us catch any GNU C dependancies, in case someone
aggressive writes a smaller, faster, or unencumbered C compiler that
meets our needs.
