I think it'd be interesting what's less demanding.
I suppose "< 0" is more efficient, as there's only a check to the
sign-bit, whereas comparing two integers (== -1) involves at
most 8 bit-operations for an 8 bit integer (others respectively).
Thus, I'd go for "< 0", but I'm open for your suggestions.
