I use shell-scripts that define the environment variables 
(ADA_INCLUDE_PATH), then do "gnatmake" without -I options. There 
are different scripts for different versions and configurations of 
the Ada programs. These script files are under configuration control.

I don't have as many directories and subdirectories as Christoph, 
so I don't (yet) need to write recursive directory traversal 
algorithms in these scripts, but it would be possible to do so and 
get the equivalent of the project-file construct "take all units in 
directory x and its subdirectories".
