Head meets wall repeatedly with mingw cross-compiling.  This is actually my first time ever attempting such a thing; the last time I needed a Windows binary, a significant number of years ago, I used MSVC on a Windows machine.

I want to help Windows users get spiffy new Segwit addresses; but I think I’ve spent enough time on that for now, whereas I should be writing documentation and improving the code.  If anybody who has a working mingw setup (including a POSIX regex package) on any platform could at least confirm that it compiles that way, I’d appreciate knowing that such a thing is possible without significant code changes before I spend more time trying.

If I can successfully produce a Windows binary myself, I will distribute it on Github PGP-signed using the ECC key identified in my signature.
