* gencode.c (build_instruction, case JUMP): Truncate PC to 32 bits.
	* interp.c (CHECKHILO): Define away.
	(simSIGINT): New macro.
	(membank_size): Increase from 1MB to 2MB.
	(control_c): New function.
	(sim_resume): Rename parameter signal to signal_number.  Add local
	variable prev.  Call signal before and after simulate.
	(sim_stop_reason): Add simSIGINT support.
	(sim_warning, sim_error, dotrace, SignalException): Define as stdarg
	functions always.
	(sim_warning): Delete call to SignalException.  Do call printf_filtered
	if logfh is NULL.
	(AddressTranslation): Add #ifdef DEBUG around debugging message and
	a call to sim_warning.
