Well, bad news and good news. The bad: We get the wrong results when just
removing HAVE_BUGGY_STRTOF. The good: That is just because we haven't applied
enough, or the right, magic. To have mingw to not interfere with things one
also has to pass -D_UCRT and -lucrt - then the tests pass, even without
HAVE_BUGGY_STRTOF.
I think this might also explain (and fix) some other oddity we had with mingw
that I was getting confused about a while back, but I forgot too much of the
details...
