That's scary, but after some little googling I've found some nice pieces of
info.

It seems that mingw has an option to support msvc vtable layout, so that you
can use COM objects. So, as long as you only export pure interfaces, you
should be safe.

However, I'm not on using pure interfaces only. I also use interface
inheritance and virtual destructors... I don't know how those affect the
layout of the vtables and if they will still be compatible. Does somebody
know what can and can't be done?
