gnatsym.adb: Update Copyright notice 

2007-04-20  Vincent Celier  <celier@adacore.com>

	* gnatsym.adb: Update Copyright notice
	(Parse_Cmd_Line): Accept new switch -D
	(Gnatsym): In Direct policy (switch -D) copy reference file to symbol
	 file.

	* prj.ads (Policy): New policy Direct
	(Yes_No_Unknown): New enumeration type
	(Project_Data): New component Libgnarl_Needed

	* prj-nmsc.adb (Check_For_Source): When recording a source file make
	use the untouched pathname casing.
	(Get_Directories): Ensure that the Display_Exec_Directory is using the
	proper casing on non case-sensitive platforms like Windows.
	(Get_Unit): Accept file names x__... and x~... (where x = a, g, i or s)
	on all platforms, as it is not possible to know which one is allowed
	before processing the project files.
	(Check_Stand_Alone_Library): Check that Library_Reference_Symbol_File is
	specified when symbol policy is Direct. Check that when there is a
	symbol file defined (either by default or with attribute
	Library_Symbol_File) it is not the same as the reference symbol file.
	(Check_Stand_Alone_Library): Recognize new symbol policy Direct.
	(Look_For_Sources): Allow Locally_Removed_Files to be declare in non
	extending projects.
	(Record_Ada_Source): Record a source that has been locally removed in an
	imported project.

	* symbols.ads (Policy): New policy Direct

	* symbols-vms.adb (Initialize): Take new policy Direct in case
	statement
