I don't understand Bruno's comments.  He probably thinks that the
Windows build uses the Posix configury, otherwise he would have
realized that, with the single exception of process.c, none of the
patched files is used in the Windows build.

So it looks like all we need to do for the native Windows build is
define socket_t and that's it.  Or did I miss something?

As for the MS-DOS build of Emacs, it does not support networking, and
in fact does not even compile the parts of process.c that are being
changed (it has `subprocesses' undefined).  So this is surely
irrelevant for that port.

I don't know enough about Cygwin to provide any feedback on this.
