Thanks for the patch.

For the record, here's Linus Torvalds' opinion on this whole socklen_t confusion:
"""
_Any_ sane library _must_ have "socklen_t" be the same size as int.  Anything else breaks any BSD socket layer stuff.  POSIX initially did make it a size_t, and I (and
       hopefully others, but obviously not too many) complained to them very loudly indeed.  Making it a size_t is completely broken, exactly because size_t very seldom is the
       same  size  as  "int" on 64-bit architectures, for example.  And it has to be the same size as "int" because that's what the BSD socket interface is.  Anyway, the POSIX
       people eventually got a clue, and created "socklen_t".  They shouldn't have touched it in the first place, but once they did they felt it had to have a named  type  for
       some unfathomable reason (probably somebody didn't like losing face over having done the original stupid thing, so they silently just renamed their blunder).
