Also, the error message should not end with a period, according to the 
GNU standards (and common practice in the rest of gfortran; we have 
about six exceptions to the rule, and I'm currently regtesting a patch 
to fix them too).

(I think that should be "Cannot", as one word rather than two, as well.)

And same here with the period, as well.
