            Bug ID: 88080
           Summary: Add warning if IMPLICIT NONE is missing
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vivekrao4 at yahoo dot com
  Target Milestone: ---

I think new Fortran code should have IMPLICIT NONE in every procedure or
preferably at the beginning of a program or MODULE. I request that gfortran add
an option that warns when this is not the case. Users who want IMPLICIT NONE in
all code can convert such a warning to an error.

This is, of course, an enhancement request and not a bug report.
