+ * interp.c (sim_stop): Set the sim's exception
+ to SIGINT.

+1999-04-02 Keith Seitz <keiths@cygnus.com>
+
+ * interp.c (UI_LOOP_POLL_INTERVAL): Define. Used to tweak the
+ frequency at which ui_loop_hook is called.
+ (ui_loop_hook_counter): New global defined when NEED_UI_LOOP_HOOK
+ is defined.
+ (sim_resume): Call ui_loop_hook (if defined) when the interval
+ passes.
+ * Makefile.in (SIM_EXTRA_CFLAGS): Include NEED_UI_LOOP_HOOK.

* Makefile.in: Define NL_TARGET so that targ-vals.h will be used
