Thanks. (In future, don't bother including the generated files - 
Makefile.in, configure, etc - with the patch.), just mention them in the 
changelog. Do you have a copyright assignment for GCC on file? If not, 
see http://gcc.gnu.org/contribute.html

I'm not entirely sure myself, but I think basically "aclocal" should be 
able to find the AM_PATH_GTK macro which GTK will install into your 
autoconf path somewhere into libjava's aclocal.m4. That macro then 
determines where GTK is located and what version it is. The best thing 
to do would be to look at some simple package that uses GTK and look at 
its configure.in.

I think the way is simply to add `gtk-config --libs` to the link 
command, and also `gtk-config --cflags` to the compiler command for the 
.cc files.
