            Bug ID: 92533
           Summary: [F2018] Permit module names in access-stmt
                    (public::/private::)
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Keywords: rejects-valid
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
  Target Milestone: ---

Fortran 2018 now permits:

module A
  use B
  private :: B

Namely,
R827  access-stmt  is  access-spec[ [ :: ]access-id-list]
C870 (R828) Each access-name shall be the name of a module, variable,
procedure, derived type, named constant, or namelist group.

Fortran 2008 had:

R524  access-stmt  is access-spec[ [ ::  ]access-id -list]
C563(R525) Each use-name shall be the name of a named variable, procedure,
derived type, named constant, or namelist group.

Currently, the code gets rejected with:
   Error: PRIVATE attribute applied to MODULE …
or Error: PUBLIC attribute applied to MODULE …
