	* gnat1drv.adb (Adjust_Global_Switches): Move setting of flags for
	Alfa mode before general treatment of flags, so that overflow checks
	settings are set appropriately in Alfa mode. Also set the mode to
	STRICT in Alfa mode if not already set by the user.

	* sem_ch10.adb (Build_Limited_Views): Even though the unit is
	not analyzed, place its entity on the name in the with clause,
	so that warnings on unused with-clause are properly supported
	for limited withs.

	* gnat_ugn.texi: Update overflow description. Pragma
	Overflow_Checks changed to Overflow_Mode.
