Integer conversions too pedantic in 64-bit

[Andrej Mitrovic]

The question is then do you want to be more consistent with the
language (abolish size_t and make something nicer), or be consistent
with the known standards (C99 ISO, et all.).

I'd vote for a change, but I know it will never happen (even though it
just might not be too late if we're not coding for 64 bits yet). It's
hardcoded in the skin of C++ programmers, and Walter is at least one
of them.
