2006-02-13 Arnaud Charlet <charlet@adacore.com>

	    Robert Dewar  <dewar@adacore.com>

	* a-exexpr.adb, a-exexpr-gcc.adb
	(Process_Raise_Exception): Removed, merged with Propagate_Exception.
	(Propagate_Exception): Now take extra From_Signal_Handler parameter.
	Remove code unused for exception propagation for the compiler itself
 	from a-except.adb and update to still share separate packages.

	* a-except.ads, a-except.adb: Ditto.
	Add comments that this version is now used only by the compiler and
	other basic tools. The full version that includes the Ada 2005 stuff
	is in separate files a-except-2005.ads/adb. The reason is that we do
	not want to cause bootstrap problems with compilers not recognizing
	Wide_Wide_String.
	Add exception reason code PE_Implicit_Return
	Add new exception reason code (Null Exception_Id)

	* a-except-2005.adb, a-except-2005.ads: New files.

	* s-wchcon.ads: (Get_WC_Encoding_Method): New function.

	* s-wchcon.adb: New file.

	* Makefile.in (LIBGNAT_SRCS): Add tb-gcc.c.
	(traceback.o deps): Likewise.
	(SPARC/Solaris): Accept sparc[64|v9]-sun-solaris.
	Activate build of GMEM instrumentation library on VMS targets.
	(gnatlib-sjlj, gnatlib-zcx): Pass EH_MECHANISM to make gnatlib.
	Use a-except-2005.ads/adb for all run-time library builds unless
	specified otherwise.
	[VMS] (LIBGNAT_TARGET_PAIRS_AUX1,2): Rename s-parame-vms.ads to
	s-parame-vms-alpha.ads and add s-parame-vms-ia64.ads.
	Use s-parame.adb on all native platforms.
	Use s-parame-vxworks.adb on all vxworks platforms.
	Add env.c env.h in LIBGNAT_SRCS
	Add env.o in LIBGNAT_OBJS
	(GNATMAKE_OBJS): Remove ctrl_c.o object.
	(LIBGNAT_TARGET_PAIRS for x86-vxworks): Use an specialized version of
	s-osinte.adb, s-tpopsp.adb, and system.ads for the run time that
	supports VxWorks 6 RTPs.
	(EXTRA_GNATRTL_NONTASKING_OBJS for x86-vxworks): Remove the use of
	i-vxworks and i-vxwoio from the run time that supports VxWorks 6 RTPs.

	* types.h, types.ads (Terminate_Program): New exception
	Add comment on modifying multiple versions of a-except.adb when the
	table of exception reasons is modified.
	Add exception reason code PE_Implicit_Return
	Add new exception reason code (Null Exception_Id)

        * clean.adb (Initialize): Get the target parameters before checking
        if target is OpenVMS. Move the OpenVMS specific code here from package
        body elaboration code.
