+       Apollo native support (untested).
+
+       * a68v-nat.c, nm-apollo68[bv].h: new files.
+       * xm-apollo68[bv].h (FETCH_INFERIOR_REGISTERS): removed.
+       * xm-apollo68b.h (PTRACE_IN_WRONG_PLACE): removed.
+       * a68v-xdep.c: removed.
+       * config/apollo68[bv].mh (XDEPFILES): removed infptrace.o
+         inftarg.o fork-child.o a68v-xdep.o.
+         (NAT_FILE, NATDEPFILES): new macros.
+
        * defs.h: include nm.h.
        * coredep.c, infptrace.c, procfs.c, rs6000-nat.c, sparc-nat.c,
          sparc-tdep.c, : do not include nm.h.
