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.
