[Bug fortran/20884] New: error needed

[jv244 at cam dot ac dot uk]

The following is non-standard and the compiler should probably generate a
warning/error with '-pedantic -std=f95'


MODULE TEST
   INTERFACE OPERATOR (.EqualTo.)
     MODULE PROCEDURE Is_Equal_To_Single
   END INTERFACE OPERATOR (.EqualTo.)
CONTAINS
 ! should be a function 7.3
 SUBROUTINE Is_Equal_To_Single(x,y)
   real :: x,y
 END SUBROUTINE
END MODULE
END

------- Comment #3 from tkoenig at gcc dot gnu dot org  2006-05-31 20:22 -------
This is caught on mainline:

$ gfortran qq.f90
 In file qq.f90:3

     MODULE PROCEDURE Is_Equal_To_Single
                                       1
Error: User operator procedure 'is_equal_to_single' at (1) must be a FUNCTION
 In file qq.f90:3

     MODULE PROCEDURE Is_Equal_To_Single
                                       1
Error: First argument of operator interface at (1) must be INTENT(IN)
 In file qq.f90:3

     MODULE PROCEDURE Is_Equal_To_Single
                                       1
Error: Second argument of operator interface at (1) must be INTENT(IN)

This was also fixed by the fix for PR 27122.
