	* bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
	Increment Warnings_Detected.  It was decrementing, which is
	wrong since we just issued a warning message.
	* binderr.ads (Errors_Detected, Warnings_Detected): Declare
	these variables to be of subtype Nat instead of Int, because
	they should never be negative.
