"Lean" is a bit of a joke. A rather smaller set of Windows
definitions can be included by defining an architecture-identifying
macro (e.g. _X86_ for i386) followed by:
#define NOMINMAX // inhibits definition of min and max macros in
#include <stdarg.h> // <winbase.h> requires definition of va_arg
Unfortunately this still defines quite a few macros.
The MSDN Library documentation of Win32 functions will tell you
about any additional headers that need to be included, even though
it recommends you include <windows.h> instead.
