Mmm, will check ...

I had a problem, the pkg-config -cflags of the gtk+ stuff is in a wrong
directory (/target/build/...). Is this a bad installation of my part,
the wrong pkg-config you spoke about, or is there something wrong with
these packages ? 

I will try checking the pkg-config database by hand.

A, ok. I just built the bytecode compiler, which should be enough for
me, i think.

Not only, first we need cross compiled gtk+ packages. I will see with
the mingw32 debian packagers what can be done, there is also a
debian-mingw32 mailing list i think.

Ok, i will.
