outl() takes an "int" not a "size_t".   You're avoiding the warning,
but on 64-bit, for example, you're silently allowing the compiler
to accept chopping off the top 32-bits of the 64-bit pointer address
off.

The warning is valid, this code won't work in certain environments,
and killing the warning is just papering over the problem such that
it will never get addressed properly.

I'm not applying patches like this, sorry.
