Don't bother.  Hardly anyone but me regularly builds on GNUStep.  And I
can't use it anyway - too many other problems.

I suppose so.  Maybe I find a way to splice in some code tailored for
GNUStep.  But it will have low priority.

I'll give you some feedback when I'm back there.  One problem with
NSTRACE I have is that it clutters output with ns_update_window_begin
and ns_defined_color entries.  I now started to comment them out one by
one.  Maybe you could devise a method to display these optionally only.

It's a bad interaction between GNUStep and the window manager.  Maybe I
can find out more.

Meanwhile please install your changes.
