Done.

Make it so this file is only built for windows.

[lanwei, 2017/06/22 18:38:45]

Yes, because we only test WM_POINTER on Windows.

Sorry if it I wasn't clear. The one test you have in this file is only run on
windows (because of the ifdef). Instead of having the ifdef you should make it
so the file is only compiled and run on windows. That way no ifdef is needed,
and other platforms aren't compiling a file they won't run .
