The current solution also fails from time to time. And there would  
switch to disable this gtk-config calling (just like there are  
switches to disable assembling and/or linking).

Yes, I prefer that unless the existing solution is so bad it fails  
almost all the time, or if the alternative is at least as versatile/ 
compatible and has significant advantages. Most of the messages about  
*config failing is that the script isn't found at all by the  
configure script, which would be a non-issue for us.

The "backup" must be maintained anyway for libraries which do not  
come with such a script.

I see this rather as complementary to supporting the *config scripts:  
if the *config scripts fail, and if the library names defined in the  
units are wrong, then you can still work around it with these options.
