	* system-vms.ads, system-vms-zcx.ads: Remove old unused VMS system
	packages.
	* system-vms_64.ads, system-vms-ia64.ads: Minor reformatting.
	(pragma Ident): Add a default ident string in the private part.

	* cstand.adb: Minor reformatting.

2010-06-22  Ed Schonberg  <schonberg@adacore.com>

	* freeze.adb (Build_And_Analyze_Renamed_Body): For expansion purposes,
	recognize the Shift and Rotation intrinsics that are known to the
	compiler but have no interface name.

2010-06-22  Geert Bosch  <bosch@adacore.com>
