What's the BSS? I zeroed the jmp_buf, and one other value declared as extern in
main.h; I've presumably missed something, as it behaves differently on the 2nd
invocation, but what?

I've moved the switch; most of the switch is
case foo: set_cmd(&cmd, foo); break;
but there are other variables set. How do I deal with that? Comment out things
that don't meet this pattern (and leave in main a trimmed-down switch to pick
up the slack?) Giving the switch a long signature with pointers to all those
values looks like a losing solution; I could also make the variables global.
