Read the RATIONALE section in POSIX on socklen_t. All of the functions
that take socklen_t arguments originally took int. The problem was
that a few vendors decided to change their implementations to use a
new type that would be the system wordsize, so POSIX mandated a
socklen_t so that either behavior could be acceptable. But int is the
correct type for socklen_t.

Hope I got that mostly accurate... It's from memory, too tired to look
it up at the moment.
