It depends a little bit on what you are distributing. If you are distributing
"some GNOME libs I'm trying to port to Windows, but are currently broken",
then you have a lot of leeway. It's broken, so they can't build it anyway.
But if it wasn't broken (or at least not intended to be broken), then
everything in the software chain down to the OS must be GPL compatible.
What exactly this "systems software" clause covers is a topic of minor debate.
The FSF argued in the past that the Qt library did not count, even for
systems where it was installed by default. On the other hand, the MFC
libraries do count, even though they do not ship with the OS.
In my opinion, as long as this software is broken, you don't have to
distribute anything it depends on, since it can't, by definition, depend on
Standard Disclaimer: I am not a lawyer. Even if no one is paying you to do
this coding, you should still hire an expensive attorney to review the GPL
and advise you in all legal matters pertaining to your porting activities. At
least that's what my attorney told me.
