Attempt to fix really bad code (return-without-value and pre-ANSI function heads).

lrsnashlib.c:55:5: warning: 'return' with no value, in function returning non-void
	return; [multiple instances]
lrslib.cpp:1485:54: error: invalid conversion from 'void (*)()' to '__sighandler_t {aka void (*)(int)}' [-fpermissive]
        errcheck ("signal", signal (SIGALRM, timecheck)); [multiple]
