[Bug 51802] Theming on 16-bit application breaks their UI

--- Comment #2 from [e-mail] ---
I was using the official unstable builds from the Wine repos for Debian, so if
they're built with MinGW then yes? I've switched back to stable for now.

I'm not exactly what the regression would have been, but I picked UXTheme
because the problem started precisely when the Windows XP-style theme engine
started applying itself to my 16-bit applications. Of course, this change might
have been triggered elsewhere.
