Fix for this PR

Thanks for reporting this. The patch "fingered" in comment #4 is certainly
responsible for this regression. In particular, it is the first chunk in
resolve.cc that is the culprit.

The attached patch feels to be a bit of sticking plaster on top of sticking
plaster and so I will go back to hunt down the root cause of these
namespace-less symbols.

I fear that you will have to make your procedures impure for the time being or,
if you don't need the added finalization features, revert to a previous version
of gfortran.

Regards and apologies for the inconvenience.

Paul
