There are some new integer types in the Windows API to support Win64. They haven't always been suppoprted; e.g. they aren't present in MSVC6.

How can I write an #if condition to detect if these types are supported by <windows.h>?

(My code needs to compile under many different versions of Microsoft Visual C++, including MSVC6. So I need to provide my own definitions of these types, with an #if to disable them in newer compilers).

Python rather stupidly has a pragma directive in its include files that forces a link against python26_d.lib when the DEBUG preprocessor variable is defined.
