[webkit-dev] JSImmediate.h 64 bit compatibility problem?

[Paul Pedriana]

I see the following code, which works for 32 bit but not 64 bit. Is 
there another file or function somewhere that's for 64 bit?

    static bool isNegative(const JSValue* v)
    {
        ASSERT(isNumber(v));
        return reinterpret_cast<uintptr_t>(v) & 0x80000000;
    }
