Generating temporary CUDA C file name fails on Windows.

OSICAT does not support MKTEMP on Windows, we can't get temporary CUDA C file name with it.

IDK if you want to add another dependency, but cl-fad has a suite of functions for making temporary files, and it works well on Windows and *nix alike: http://weitz.de/cl-fad/#temporary-files

Thanks! I will follow your suggestion.
