Using Visual Studio 2008 and its C/C++ compiler, how do I create a Win32 DLL that is dependent only on other Windows DLLs, and has no dependency on the Microsoft C runtime?

I have some C code I want to place in a DLL that is entirely computation, and makes almost no use of C library functions.

For those it does use (eg memcpy), I'm happy to rework the code to use the Win32 API equivalents (eg CopyMemory).
