You would have thought so but.. I get

makedepend: warning:  utils.c, line 69: cannot find include file
probably due to makedepend not knowing about __MINGW32__ at that point in
the file (with my archaic build).
Not that important..but I just like clean builds and check by diff'ing new
and old build logs looking
for additional crud!

That crashes for me.
I use winMultiWindowGetTransientFor() like this in winmultiwindowwindow.c to
confirm that if an X window
has a parent and that Microsoft Windows agrees that this parent is in the
foreground, all is well before
creating the child in Windows 
i.e. a double check to not assign a parent wrongly to a Microsoft window.

HWND                  hFore = NULL;
WindowPtr             pDaddy;
if (winMultiWindowGetTransientFor (pWin, &pDaddy))
      if (pDaddy)
        hFore = GetForegroundWindow();
        if (hFore && (pDaddy != (WindowPtr)GetProp(hFore, WIN_WID_PROP)))
hFore = NULL;
and then use hFore in CreateWindowExA(...,HWND hWndParent,...)
OK to be NULL

A case of calling with pp's and using p's I think?
