	* Makefile.in: Set EH mechanism to ZCX for FreeBSD.
	(NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
	possible.
	(a-except.o): Pass it to the compiler.
	(gnatlib-shared-vms): Removed -nostartfiles switch in link step.
	(LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
	a-calend-mingw.adb version.

        * Makefile.rtl: Added s-dsaser.
	Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
	(GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
	Ada.Dispatching.Round_Robin.
	Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists

	* Make-lang.in: Remove all references to gt-ada-decl.h.
	Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler
	sources.
	Add dependency on ada/s-restri.o for GNAT1 and GNATBIND objects.
	Update dependencies.

	* system-freebsd-x86.ads: Make ZCX the default EH mechanism for FreeBSD
