Subject: [PATCH] Fix message boxes with wxYES_NO|wxCANCEL style in wxMSW

Windows CE code removal in 8282c1be0f358f5fa00c6aab21c3298af7d8ce02 (see
https://github.com/wxWidgets/wxWidgets/pull/81) broke message boxes showing
"Yes", "No" and "Cancel" buttons at once, add accidentally removed code back.

Closes https://github.com/wxWidgets/wxWidgets/pull/139
