        PR fortran/40011
        * error.c : Add static flag 'warnings_not_errors'.
        (gfc_error): If 'warnings_not_errors' is set, branch to code
        from gfc_warning.
        (gfc_clear_error): Reset 'warnings_not_errors'.
        (gfc_errors_to_warnings): New function.
        * options.c (gfc_post_options): If pedantic and flag_whole_file
        change the latter to a value of 2.
        * parse.c (parse_module): Add module namespace to gsymbol.
        (resolve_all_program_units): New function.
        (clean_up_modules): New function.
        (translate_all_program_units): New function.
        (gfc_parse_file): If whole_file, do not clean up module right
        away and add derived types to namespace derived types. In
        addition, call the three new functions above.
        * resolve.c (not_in_recursive): New function.
        (not_entry_self_reference): New function.
        (resolve_global_procedure): Symbol must not be IFSRC_UNKNOWN,
        procedure must not be in the course of being resolved and
        must return false for the two new functions. Pack away the
        current derived type list before calling gfc_resolve for the
        gsymbol namespace.  It is unconditionally an error if the ranks
        of the reference and ther procedure do not match. Convert
        errors to warnings during call to gfc_procedure_use if not
        pedantic or legacy.
        (gfc_resolve): Set namespace resolved flag to -1 during
        resolution and store current cs_base.
        * trans-decl.c (gfc_get_symbol_decl): If whole_file compilation
        substitute a use associated variable, if it is available in a
        gsymbolnamespace.
        (gfc_get_extern_function_decl): If the procedure is use assoc,
        do not attempt to find it in a gsymbol because it could be an
        interface. If the symbol exists in a module namespace, return
        its backend_decl.
        * trans-expr.c (gfc_trans_scalar_assign): If a derived type
        assignment, set the rhs TYPE_MAIN_VARIANT to that of the rhs.
        * trans-types.c (copy_dt_decls_ifequal): Add 'from_gsym' as a
        boolean argument. Copy component backend_decls directly if the
        components are derived types and from_gsym is true.
        (gfc_get_derived_type): If whole_file copy the derived type from
        the module if it is use associated, otherwise, if can be found
        in another gsymbol namespace, use the existing derived type as
        the TYPE_CANONICAL and build normally.
        * gfortran.h : Add derived_types and resolved fields to
        gfc_namespace. Include prototype for gfc_errors_to_warnings.
