128 bit integer with c on windows?

Is there any c compiler on windows able to use 128 bit integers natively? On example, you can use gcc on linux, with __uint128_t... any other chance on windows? (It would be great if 128 bit worked on 32 bit computers as well! :D)

In GCC you can try `` attribute ((mode(...)))`, see here and here, eg

typedef unsigned int myU128 __attribute__((mode(TI)));

The results depend on your platform, though.

You could try using SSE intrinsics built into Visual C++
