I would think so yes.

No, since the result for both functions is always taken as positive for one
or more negative arguments. However.... unless we change the interface,
it's hard to see how to accomplish this easily? Particularly as the
unsigned version has a greater range?
Note that if the arguments might be negative then you could just write:
static_lcm<(arg1 < 0 ? -arg1 : arg1), (arg2 < 0 ? -arg2 : arg2)>::value
to achieve the same effect.
