I know since I wrote plain xlib programs years ago.

That is the reason why I do not like this way very much: Code where a 
major part of development is done for the Windows operating system 
is usually not easy to compile on UNIX machines: Poor makefiles, HUGE
amount of dependencies, often not easy to have two different versions
of a library on a system due to the use of identical file names
for both versions (common "newer DLL replaced older one" on Windows
PCs).

gtk-1.0 is OK regarding speed, but recently I recomiled a program 
with 2.2 and now it runs at 30% the speed of version gtk-1.2. Anyhow
GtkAda-1.2.12 is based on 1.2, so I will give this one a try...

I know, just started this journey with libart_lgpl-1.2...

...will post the end of the story in the future,

    ...thanks so far,

         Erik.
