[Bug fortran/13257] New: [gfortran] Error instead of warning for missing comma in format string

["dann at godzilla dot ics dot uci dot edu" <gcc-bugzilla@gcc.gnu.org>]

With: gcc version 3.5-tree-ssa 20031130 (merged 20031123)

test.f90
      subroutine mysub
      dimension ibar(5)
      write (3,1001) ( ibar(m), m = 1, 5 )

 1001 format (/5x,' ',i4' '/ )
      return
      end

gfortran -c test.f90 -ffixed-form                                              
                                               In file test.f90:5

 1001 format (/5x,' ',i4' '/ )
                           1
Error: Missing comma in format string at (1)
 In file test.f90:3

      write (3,1001) ( ibar(m), m = 1, 5 )
                  1
Error: FORMAT label 1001 at (1) not defined

g77 gives a warning, but still compiles the code.

Intel's compiler compiles the above code.

Code like this appears in SPEC95
