Yesterday I downloaded and installed GtkAda and GNAT Studio again from 
the site you mentioned the error did not disappear.
In the mean time I tried to rebuild another project and it created a 
simular problem but with glib.ali
I read the stack overflow item but I think that is not the problem.
For reasons of tracebility I did not build GtkAda in the original 
directory but in C:/GNAT/GtkAda.
The last uodate of the OS was only a few days ago but after that it 
still worhed
