Hm. This fails on windows right now because the getopt_long() fallback implementation doesn't implement optional_argument. Unless people think this can be broken for a day or somebody has a better solution, I'll revert tomorrow morning. The best plan after that seems to be to add optional_argument support to getopt_long.c - looks easy enough.

Do we need a configure test for optional_argument? I don't think so, but I could see somebody arguing the other way round.
