[Bug fortran/31149] New: gfortran: no diagnostics about too many arguments in legacy code (vs. g77)

[bartoldeman at users dot sourceforge dot net]

Consider this code:

      SUBROUTINE FOO(I)
      I=0
      END

      SUBROUTINE BAR()
      CALL FOO(1,2)
      END

compiled with g77 3.4.6:

f77.f: In subroutine `bar':
f77.f:1: 
         SUBROUTINE FOO(I)
                    1
f77.f:6: (continued):
         CALL FOO(1,2)
              2
Too many arguments passed to `foo' at (2) versus definition at (1) [info -f g77
M GLOBALS]

no object file is generated.

gfortran, even with -Wall, emits are no warnings or errors at all and an object
file is generated.

With a module or interface block gfortran does a lot better but then it is no
longer Fortran 77 of course.
