Yes - but left there on purpose: I was unsure whether I still need it or 
not. I will remove it in the final version of the patch.

Note: My current focus is on getting testing/implementation feedback on 
the patch and to fix the remaining issues. Only when everything works, I 
will clean up the patch, write a changelog and commit it.

Biggest issues currently:
* Symtree-walking issue - see separate email.
* FoX (Fortran XML) library is - again - broken. It uses two "USE, only" 
for the same module, which for some reasons breaks.
