2008-04-08  Hristian Kirtchev  <kirtchev@adacore.com>

	* a-calend-vms.ads, a-calend-vms.adb: Add with and use clause for
	System.OS_Primitives.
	Change type of various constants, parameters and local variables from
	Time to representation type OS_Time.
	(To_Ada_Time, To_Unix_Time): Correct sign of origin shift.
	Remove the declaration of constant Mili_F from several routines. New
	body for internal package Conversions_Operations.
	(Time_Of): Add default parameters for several formals.

	* a-caldel.adb: Minor reformatting

	* a-calend.ads, a-calend.adb: New body for internal package
	Conversions_Operations.
	(Time_Of): Add default parameters for several formals.

	* Makefile.rtl: Add a-ststop
	Add Ada.Calendar.Conversions to the list of runtime files.
	Add g-timsta

	* a-calcon.adb, a-calcon.ads: New files.
