Well, it also was kind of wrong before the change as well; I have 
changed it to:

    if (sym->attr.flavor == FL_PROCEDURE)
      {
-      /* Catch function declarations. Only used for actual parameters,
+      /* Catch functions. Only used for actual parameters,
          procedure pointers and procptr initialization targets.  */

I also find it a bit problematic - an explicit "external" is (slightly) 
different to implicitly using it. In any case, the original version 
causes ICEs with some testcases, e.g. bessel_3.f90.

Committed as Rev. 207854 for the trunk; I will wait a while before 
backporting to 4.8 and 4.7.
