alc.c has a recursive signal handler

[sqqqrly]

alc.c defines a function simulator(). It is used as a signal handler within alc.c. Simulator() itself can issue signals with itself as a handler. This is recursion. Does this make sense?

In order to define a signal handler, it must have this form:
void sighandlerName(int signum);

simulator() was modified to fit this definition. The recursion remains.

bf_view.c also has recursive signal handler do_view().
