That's an excellent reason for trying int *second*.

If the socklen_t typedef exists, it's almost certainly the right thing to
use.  If it doesn't exist, it won't matter whether the compiler cares for
matching prototypes because it'll be a syntax error.

I strongly suspect that the intersection of compilers that botch up the
matching prototypes with headers that typedef socklen_t is the empty set.

} It defaulted to int before - so let's stick to int as much as
} possible. May be, I'm just plain paranoid. And the whole needs check
} for general prototype support of course.

That raises the question of what SOCKLEN_T gets defined to be when NONE
of the types that are attempted work.  (It also raises the question of
whether we should be testing for HAVE_SOCKLEN_T and providing our own
typedef if not, rather than defining a SOCKLEN_T macro.)  I think the
right way to default to `int' is to fall back on it when the test fails
