longjmp() needs 2 arguments, usually 1 as second argument will do --
anything but 0 -- else check for a statement approximately like:

	if(setjmp(jmp) == val) {
		...
	}
If the `== val' part is missing, 1 will do. Hence, longjmp(jmp, 1).

(If you're at a total loss, "man setjmp" and "man longjmp" give information
on these functions -- but you have to speak a bit of C)

This fix is inferred, I don't have the code myself - Raymond
