	* exp_intr.adb (Add_Source_Info): Do not decode
	file names; they were not encoded in the first place.

	* a-tags.adb (Internal_Tag): Unsuppress checks, so we get
	exceptions instead of crashes. Check for absurdly long strings
	and empty strings. Empty strings cause trouble because they can
	have super-null ranges (e.g. 100..10), which causes Ext_Copy to
	be empty, which causes an array index out of bounds.
	* s-ststop.adb (Input): Unsuppress checks, so we get exceptions
	instead of crashes.

	* sem_util.adb (Is_CCT_Instance): allow use in
	the context of protected types.

	* a-tigeli.adb: minor remove extra whitespace.
