re PR fortran/12841 (passing null to a subroutine)
fortran/
PR fortran/12841
* interface.c (compare_parameter, compare_actual_formal): Don't
check types and array shapes for NULL()
* trans-expr.c (conv_function_call): No double indirection for
NULL()
( I had accidentally committed the interface.c part before)

PR fortran/12841
* gfortran.fortran-torture/execute/null_arg.f90: New test.
