             Bug #: 51953
           Summary: [F2008] Allow multiple allocate-objects in ALLOCATE
                    with SOURCE=
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: rejects-valid
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: burnus@gcc.gnu.org


Fortran 2003 had:

C631 (R623) If SOURCE= appears, type-spec shall not appear and allocation-list
shall contain only one allocate-object, which shall be type compatible
(5.1.1.2) with source-expr .


Fortran 2008 has this is gone; one just has:

C637 (R626) At most one of source-expr and type-spec shall appear.
C638 (R626) Each allocate-object shall be type compatible (4.3.1.3) with
source-expr. If SOURCE= appears, source-expr shall be a scalar or have the same
rank as each allocate-object.


gfortran checks this for SOURCE=  (but not for MOLD= which is a F2008 feature):

  SOURCE tag at (1) requires only a single entity in the allocation-list

Expected: Check this only for -std=f2003.
