            Bug ID: 96583
           Summary: F2018 changes to get_environment_variable
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: markeggleston at gcc dot gnu.org
            Blocks: 85836
  Target Milestone: ---

Fortran 2003 and Fortran 2008:

Arguments LENGTH and STATUS shall be default integer scalars.

Fortran 2018:

Arguments LENGTH and STATUS shall be a scalars of type integer with a decimal
exponent range of at least four.

New argument:

ERRMSG (optional) shall be a default character scalar. It is an INTENT (INOUT)
argument. It is assigned a processor-dependent explanatory message if the
optional argument STATUS is, or would be if present, assigned a positive value.
Otherwise, it is unchanged. Not currently supported by gfortran 11.

---

For -std=f2003 and -std=f2008 LENGTH and STATUS arguments should be rejected if
they are not default integer scalars, gfortran 11 produces "type mismatch in
argument" error messages.

For -std=f2018 and -std=gnu LENGTH and STATUS arguments should only be rejected
if the is integer(1).
