2003-12-17  Ed Falis  <falis@gnat.com>

	* a-elchha.adb (Tailored_Exception_Information): made Info constant to
	eliminate warning.

	* a-exextr.adb: Add context clause for
	Ada.Exceptions.Last_Chance_Handler.

2003-12-17  Sergey Rybin  <rybin@act-europe.fr>

	* cstand.adb (Create_Standard): Change the way how the declaration of
	the Duration type is created (making it the same way as it is for all
	the other standard types).

2003-12-17  Robert Dewar  <dewar@gnat.com>

	* s-crtl.ads: Fix header format
	Change Pure to Preelaborate

2003-12-17  Ed Schonberg  <schonberg@gnat.com>

	* checks.adb (Selected_Length_Checks): Generate an Itype reference for
	the expression type only if it is declared in the current unit.

	* sem_ch3.adb (Constrain_Index): Handle properly a range whose bounds
	are universal and already analyzed, as can occur in constrained
	subcomponents that depend on discriminants, when one constraint is a
	subtype mark.

	* sem_res.adb (Resolve_Type_Conversion): Any arithmetic expression of
	type Any_Fixed is legal as the argument of a conversion, if only one
	fixed-point type is in context.

2003-12-17  GNAT Script  <nobody@gnat.com>

	* Make-lang.in: Makefile automatically updated
