Is there any way to do 128-bit shifts on gcc <4.4?

gcc 4.4 seems to be the first version when they added int128_t. I need to use bit shifting and I have run out of room for some bit fields.

Edit: It might be because I'm on a 32-bit computer, there's no way to have it for a 32-bit computer (Intel Atom), is there? I wouldn't care if it generated tricky slow machine code if I would work as expected with bit shifting.
