Allow for platforms that have optreset but not <getopt.h>.

Browse Source 
Reportedly, some versions of mingw are like that, and it seems plausible
in general that older platforms might be that way.  However, we'd
determined experimentally that just doing "extern int" conflicts with
the way Cygwin declares these variables, so explicitly exclude Cygwin.
