What result do you get?

Really? Could you just type "round" at the REPL and show us what methods you get? There's nothing in the two/three-arg round code that refers to 64-bit anything. It's generic to Integer. 

Are you building on that machine? Does "make test" work?

Two-argument round/ceil/floor/trunk were pretty recent additions, and might not be in the Windows binary release yet.

If you need them now, you can use this snippet:

for f in (:round, :ceil, :floor, :trunc)
    @eval begin
        function ($f)(x, digits::Integer, base::Integer)
            og = _round_og(digits, base)
            ($f)(float(x) / og) * og
        end
        ($f)(x, digits) = ($f)(x, digits, 10)
    end
end

They are in current master on windows, though probably not yet in the binary distributions. Jameson is working on creating new binaries atm and I'll join in myself later, to try to get this figured out.
