Log message:
	sysdep reduction:
	struct linger is identical on all platforms except Cygwin (where it doesn't appear to be Posix-conforming)
	Posix says the fields are int, but Cygwin uses unsigned short.
	assert this (in UnixC.c)
	use a copying wrapper on Cygwin (Usocket.c)
	remove platform specific code, except for Cygwin (#ifdef a few lines instead of duplicating stuff for every platform)
