+ * breakpoint.c (remove_breakpoint): Change error to warning so
+ that hardware watchpoint removal problems won't leave breakpoint
+ traps in the target.
+ * configure configure.in: Make --enable-gdbtk be the default.
+ * remote-e7000.c (e7000_insert_breakpoint,
+ e7000_remove_breakpoint): Use e7000 based breakpoints, not memory
+ breakpoints.
+ * (e7000_wait): Adjust PC back by two when we see a breakpoint to
+ compensate for e7000 maladjustment.
+ * sparcl-tdep.c (sparclite_check_watch_resources): Fix logic bug
+ which prevented hardware watchpoints from working.
