	* sem_ch12.adb (Analyze_Formal_{Floating_Type,
	Signed_Integer_Type,  Decimal_Fixed_Point_Type, Discrete_Type}):
	Use sloc of defining identifier of farmal type declaration,
	as sloc of generated internal entity, to prevent misplaced
	references in ali.

2011-10-13  Ed Schonberg  <schonberg@adacore.com>

	* sem_intr.adb (Check_Intrinsic_Operator): Check that type
	is fully defined before checking that it is a numeric type.

2011-10-13  Ed Schonberg  <schonberg@adacore.com>

	* sem_aggr.adb (Resolve_Record_Aggregate): If a component
	association for component X has a box, then X is covered in the
	aggregate even if there is not default value for X in the type
	declaration, and X has to be default-initialized.

2011-10-13  Ed Schonberg  <schonberg@adacore.com>

	* sem_attr.adb (Check_Enum_Image, Analyze_Attribute case
	'Value): Mark literals as referenced only if reference is in
	current source unit.

2011-10-13  Matthew Heaney  <heaney@adacore.com>

	* a-csquin.ads (Enque, Dequeue): Mark interface operations as entries.

2011-10-13  Olivier Hainque  <hainque@adacore.com>

	* sigtramp.h: New file.  Prototype and spec of the signal
	trampoline to be called by an established handler to provide
	dwarf call frame info before the real signal processing code.
	* sigtramp-ppcvxw.c: New file.	Implementation of the signal
	trampoline for ppc-vxworks.
	* init.c (vxworks section): Use it for ppc.
