Some time ago, I tried to port cyrus-sasl to mingw (mostly for fun), I remember I was very sadden by their build-sys which would really need some serious love.


At that time the git repo wasn't even public. And given the enthusiasm (I got no reply), and the lack of interest, I left it there (apparently, just one commit made its way upstream)

There are some binary distribution for Windows around, so it must be doable, but not so easily imho. What mechanism would you rely on? Testing all of them can be tedious too.
