[Mingw-cross-env-list] gtk3 and gtkmm3

[Gerardo Ballabio]

Hello,
is anyone working on building Gtk+ and gtkmm version 3 with MXE?
I'm willing to try myself if necessary, but I cannot guarantee that
I'll be able to succeed, and I'd avoid wasting time on duplicating
work if someone else is already doing it.
Has anyone tried? Are there known problems?

Thank you
 Gerardo
