CUB code doesn't compile with CUDA 5.0 on Ubuntu Linux 11.10

[harrism]

I ran into this in my own code, and then tried the CUB tests, and they fail to compile too.

Thanks Mark. It’s fixed now.

(Unlike the snapped release branches, I hadn't been good at making sure the main branch is passing all tests on all platforms after adding new features.)

Thanks. Verified fixed.
