AFAIK, it's needed. If you build an application using native windows
calls you need to include windows.h. But you _never_ should include
winsock.h when linking against cygwin1.dll since the socket calls
colide then. Except inside of Cygwin which obviously needs winsock.h.

So the problem here is not building cygwin itself but to build a cygwin
application using both, native windows calls and cygwin socket calls.
