I compiled that now as a very first test on an openSUSE 11.4 32 bit in a
virtual machine without errors (which took a while since I first had to
setup the dev version of octave there). 
So far I only did a quick test that I can activate 'graphics_toolkit qt'
and show a plot with it which also succeeded. I will continue tomorrow
to have a look at the ui* features and will then also have a look in
making it work on my original 64 bit system.
