Hm, where did you get this?  Because it does have optreset, albeit in a
gratuitously ABI-incompatible fashion:

However, I pulled down the allegedly current mingw source tarball from
sourceforge, and what I found in it is an older version that has *not*
got that change.  The CVS tree there doesn't seem to have it either.
So I'm disinclined to want to rely on setting _BSD_SOURCE, as I first
thought might be the answer --- it looks to me like only some versions
of mingw will respond to that.
