The 286 will segment fault every time if null is not cast properly.
Try casting the terminating null arg to (char *):

execl(emprog[1],"Empire",cnumbuf,"","1","\0377",(char *)0); 

BTW, I'm curious about the "\0377" arg.  Does empire have a command line
option which takes a 1 char string with -1 as its contents ?
