WINDOWS_LEAN_AND_MEAN: There is no such symbol, although a very few

MSDN sample programs use it, apparently in error.  The correct name
is WIN32_LEAN_AND_MEAN.  After switching to the correct name, in two
cases more was needed because the code actually relied on things that
disappear when WIN32_LEAN_AND_MEAN is defined.
