Hm, buildfarm member narwhal doesn't seem to be having any such problem.
(It's got its own issues, but not this.)

Do you think you could put up a buildfarm critter using whatever version
of mingw you're using?  Without buildfarm feedback, things *will* break
regularly; Windows is just too weird to expect otherwise.

I'm a bit suspicious of this patch because of the comment in pg_getopt.h
saying that cygwin doesn't want those variables to be declared.
We can try it, but the lack of up-to-date cygwin members in the buildfarm
means we won't be real sure whether it breaks cygwin.

Of course, I guess the response to any complaints can be "please put
up a buildfarm member" ...
