-**
-**  A reliable implementation of signal for System V systems.
-**
-**  Two functions are provided, xsignal and xsignal_norestart.  The former
-**  attempts to set system calls to be restarted and the latter does not.
-**
-**  Be aware that there's weird declaration stuff going on here; a signal
-**  handler is a pointer to a function taking an int and returning void.
-**  We typedef this as sig_handler_type for clearer code.
