            Bug ID: 79852
           Summary: diagnostics should not end with exclamation mark
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roland.illig at gmx dot de
  Target Milestone: ---

from fortran/decl.c:

gfc_error ("%qs at %C is already defined as FINAL procedure!", name);

Having a few diagnostics end with an exclamation mark makes them stick out
although they are nothing special.

All diagnostics in all files (not only Fortran) should not end with punctuation
(except for the occasional "did you mean %qs?").
