Oooo, I just focussed on libc and kernel versioning but forget gtk+ ...
I am using 1.2.3 and XFree86 3.3.3 for libc5 installed by myself from the
website. (I have started with a SuSE from 1985 upgrading it by myself, so
nearly nothing from the start system is there)

and to bring two answers together:

O.k. thats very clear. But I don't use threads!!! Just link with -lpthread
(namely as a test the testgtk: only added `glib-config --libs gthread` to
testgtk_LDADD) and testgtk bombs out in gtk_main().

So behaves grip. I have commented out all pieces of code that uses threads but
leave the linkage in the makefile. ldd shows libgthread and libpthread.

But there are ways to signal the window-manager my wishes from inside an
application, like for iconifying or positioning.  Is there no chance to give a
hint for maximizing the window???

I don't think so.  I have a vbox (scrolled_window) with a variable line-count
(the number doesn't change while the programm is running only at startup) and I
want the widget be as small as possible or of fixed size.  Say I have the place
for 8 lines. When I have to display 5 lines I want the widget of size 5, but
with 10 lines I do want it of size 8 (and the scrollbar appear).
