	PR fortran/33541
	*interface.c (compare_actual_formal): Exclude assumed size
	arrays from the possibility of scalar to array mapping.
	* decl.c (get_proc_name): Fix whitespace problem.

	PR fortran/34231
	* gfortran.h : Add 'use_rename' bit to symbol_attribute.
	* module.c : Add 'renamed' field to pointer_info.u.rsym.
	(load_generic_interfaces): Add 'renamed' that is set after the
	number_use_names is called.  This is used to set the attribute
	use_rename, which, in its turn identifies those symbols that
	have not been renamed.
	(load_needed): If pointer_info.u.rsym->renamed is set, then
	set the use_rename attribute of the symbol.
	(read_module): Correct an erroneous use of use_flag. Use the
	renamed flag and the use_rename attribute to determine which
	symbols are not renamed.
