* gcc-interface/decl.c (choices_to_gnu): Rename parameters.  Deal with
	an operand of Character type.  Factor out range generation to the end.
	Check that the bounds are literals and convert them to the type of the
	operand before building the ranges.
	* gcc-interface/utils.c (make_dummy_type): Minor tweak.
	(make_packable_type): Propagate TYPE_DEBUG_TYPE.
	(maybe_pad_type): Likewise.
