	* erc32.c (sis_memory_write): Change prototype to const unsigned char *.
	* func.c (exec_cmd, event, advance_time, wait_for_irq): Use uint64
	for counts.
	* interf.c (run_sim): Change icount to uint64_t. Use strtol directly.
	(sim_resume): Specify maximum run time as uint64.
	* sis.c (run_sim): Change icount to uint64_t.
	* sis.h: Define uint64 as uint64_t. Change various fields and
	prototypes to uint64 to support longer simulations.
