	* errout.adb (Delete_Warning): Do not
	decrement Warnings_Treated_As_Errors. This is called before
	Warnings_Treated_As_Errors has been incremented to account for
	this warning. Decrementing it here can lead to negative values
	of Warnings_Treated_As_Errors, raising Constraint_Error in
	checks-on builds, and causing the compiler to return an error
	code in checks-off builds.
