	* gnatcmd.adb (GNATCmd): GNAT CHECK accepts switch -U
	If GNAT CHECK is called with a project file, but with no
	source on the command line, call gnatcheck with all the compilable
	sources of the project.
	Take into account the new command Check, for gnatcheck. Treat as for
	other ASIS tools: take into account project, specific package Check and
	Compiler switches.
	For ASIS tools, add the switches in package Compiler for
	the invocation of the compiler.

	* prj-attr.adb: Add package Check and its attributes

	* vms_conv.ads (Command_Type): New command Check, for gnatcheck

	* vms_conv.adb (Initialize): Change Params of command Check to
