It's possible, sure. I expect it's pretty obvious where you might want to
make such a change in mkpasswd.c if you're so inclined.

I'm sure. The APIs in use aren't only for Cygwin. I don't know of any
utility that you can use, off the top of my head, that would provide better
insight than debugging through the code.

Perhaps it's time to try again. In this case anyway, you wouldn't need
to build more than 'mkpasswd'. Shouldn't be too hard if you're used to
building any software. Sounds like you've done some of this before but
I may be misinterpreting.
