wincrypt.h for Pocket PC 2003 in Visual C++ 8.0

For non-Pocket PC builds, if WIN32_LEAN_AND_MEAN is not defined, including windows.h will also include wincrypt.h. However, the Pocket PC windows.h include does not itself include wincrypt.h, so you will have to explicitly include it in your source code.

#include <windows.h>
#include <wincrypt.h>
