Linux defines it as `int' as it's enforced by Linus. See the amusing
`NOTE' section in `man 2 accept':
Quoting Linus Torvalds: _Any_ sane library _must_
have "socklen_t" be the same size as int. Anything else
breaks any BSD socket layer stuff.
POSIX defines it as `int' which is correct. SUSv2 defines it as
"an unsigned opaque integral type of length of at least 32 bits."
