Make-lang.in (GNATLIBFLAGS): Add -W -Wall.

2001-11-17  Laurent Guerby  <guerby@acm.org>

	* Make-lang.in (GNATLIBFLAGS): Add -W -Wall.
	* gigi.h (init_decl_processing): Rename to gnat_init_decl_processing.
	* io-aux.c: Provide K&R prototypes to all functions, reformat code.
	* lang-spec.h: Add missing struct field to silence warnings.
	* sysdep.c (rts_get_*): Provide K&R prototype.
	* sysdep.c (Unlock_Task, Lock_Task): Move to K&R prototype.
	* traceback.c (Unlock_Task, Lock_Task): Likewise.
	* tracebak.c (__gnat_backtrace): Remove unused variable.
	* utils.c (end_subprog_body): Move to K&R style.
