Has anyone tried building for Windows?

Thanks for trying this.  As far as I know, you're the first person who's
attempted this.

The last time I did any Windows development was about 13 years ago, so
I'm somewhat rusty on the details.

IIRC, Cygwin and MingW-64 are two different approaches: AIUI, Cygwin is
a compatibility layer that makes Windows look like more like POSIX, and
MingW-64 is a build system for building "natively" for Windows.

I believe it ought to be possible to make it work, but I'm enough of a
pessimist to think that it's unlikely to work without needing some bug
fixes, so let's figure out what's needed.

AFAIK, it's only used by the jit, so it could well need some patches.

Can you post the error messages somewhere please?  (along with the
configuration(s) you're using)

Thanks
