In that case, I suppose Bruno was talking about ports for programs
other than Emacs.  Cygwin ports should include sys/socket.h, as
you wrote, and MingW ports should include some other file.  For
Emacs this shouldn't matter, since it does things its own way,
and (and you say) all that's important is that the header files
should define socklen_t one way or another.
