Fix temporary directory Temporary directory now is hard code

Dear NVIDIA developer,
On Windows, nvcc always use c:/windows/temp even the TEMP users variable is other directory.
It’s small bug, but I think it’s better to let you know.

It can be a big hassle if the user does not have a permission to write to c:/windows/temp. And even worse, if there is no drive c: )


This is a known bug which will be resolved in the next release.
