+	* solib-legacy.c (legacy_svr4_fetch_link_map_offsets): Use
+	new configure macros to choose which (if any) code to
+	compile in.  Added code to explicitly handle *BSD systems;
+	these systems were previously handled only through macro
+	redefinition.  Also, due to the way the autoconf tests are set
+	up, this function will no longer return a non-zero value when
+	GDB is configured as a cross debugger.  I.e, cross debuggers
+	will no longer be able to "accidentally" get the host system's
+	link map offsets.
