	* config/obj-som.c (adjust_stab_sections): Add prototype.
	(obj_som_compiler, obj_som_version, obj_som_copyright,
	adjust_stab_sections): Add ATTRIBUTE_UNUSED to unused arguments.
	* config/tc-hppa.c (update_subspace):  Likewise.
	(is_defined_subspace): Amplify comment.
	* config/obj-som.h (som_frob_file): Add prototype.
