Looks pretty odd, the .h and .cpp only reference the sys/socket.h, so
I can only presume this must be including cygwin/socket.h

I don't know why right now by socketstream.cpp includes the same
things as the header does.  Perhaps the ones in the .cpp could be

I'm afraid I can't do anything directly to help fix this as I have now
cygwin set up to explore here.  If we can't get it compiling soon
we'll have to disable this plugin under the Cygwin build.
