	* Make-lang.in: Add initialize.o when needed.
	Remove obsolete references to RT_FLAGS.
	Add missing dependencies for sdefault.o

	* initialize.c: New file.

	* init.c [VMS] Declare ADA$ externs weak to fix build problem in IVMS.
	[VMS] cond_signal_table: Fix problem in declaration.
	[VMS] __gnat_error_handler: rewrite.
	Move all __gnat_initialize() routines to initialize.c
	Specialize the former "hpux" section to "hppa hpux", as this is what the
	section really is here for and we now have other hpux ports that need
	different contents.
	(__gnat_adjust_context_for_raise) i386-linux: First version of this
	function for this target. Adjust PC by one in the machine context. This
	adjustment was previously done in the MD_FALLBACK_FRAME_STATE_FOR, but
	it is more reliable to do that in the signal handler itself.
	(__gnat_install_handler) i386-linux: Set SA_SIGINFO in the sigaction
	flags, so that the handler is passed the context structure to adjust
	prior to the raise.
	(__gnat_error_handler) i386-linux: Adjust the signature to match what a
	SA_SIGINFO sigaction should look like. Call
	__gnat_adjust_context_for_raise before actually raising. Cleanup unused
	Machine_State_Operations stuff.
	Add conditional code so that the x86_64 is also supported.
