Only until you have to pass the size of something to/from some other
interface.

All you're doing is moving the hurdle!  I have to write extra code to do
bounds checking because of the signed integer, and because of the loss
of precision.

It would be better to use unsigned values for sizes of things like
everything else does.  No warnings then either.


That said, I'd much prefer ssize_t to the current int.  The 2GB limit on
64bit systems would disappear, without impacting 32bit systems.
