+	* i386dynix.c, config/i386-dynix.mt:  New files, handling Dynix
+	variant of a.out.
+	* configure.in, config.bfd:  Use them for Dynix.
+	* Makefile.in:  Add dependencies for i386dynix.o. 
+	* targets.c:  Add definition for i386dynix_vec.
+	* hosts/symmetry.h:  Do not define TRAD_CORE_USER_OFFSET for Dynix.
+	Define HOST_DATA_START_ADDR and TRAD_UNIX_CORE_FILE_FAILING_SIGNAL
+	for Dynix. Remove inclusion of dynix3.h, Dynix bfd is now handled by
+	i386dynix.c
