CUDA 2.3: MSVC9: version.cu example generates "nonstandard extension" warning when C runtime DLL used about thrust HOT 2 CLOSED

I think this is nvcc's bug.  The following code which doesn't rely on Thrust 
also 
produces it:

#include <istream>

int main(void) {return 0;}

It compiles with cl.exe alone without warning.

marking as not a bug.
