	* exp_ch9.adb: Comment improvements.
	(Build_Entry_Family_Name): Add parentheses around the index of a entry
	family member.

2009-04-15  Bob Duff  <duff@adacore.com>

	* sem_warn.adb (Check_Infinite_Loop_Warning): Catch cases like
	"while X /= null loop" where X is unchanged inside the loop. We were
	not warning in this case, because of the pointers -- we feared that the
	loop variable could be updated via a pointer, if there are any pointers
	around the place. But that is impossible in this case.

	* sem_util.adb (May_Be_Lvalue): This routine was overly pessimistic in
	the case of dereferences. In X.all, X cannot be an l-value. We now
	catch that case (and implicit dereferences, too).

	* sinput-p.ads, sinput-p.adb (Clear_Source_File_Table): New procedure

2009-04-15  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Is_Actual_Of_Previous_Formal): Make fully recursive.
	From code reading.
	(Analyze_Package_Instantiation): If generic unit in child instance is
	the same as generic unit in parent instance, look for an outer homonym
	to locate the desired generic.
