Demos to demonstarte the issue of CFileDialog with bVistaStyle == true not
displaying content on osx64

With

portable-winehq-devel-5.0-osx64.tar.gz

on Mac the MFC call CFileDialog with parameter bVistaStyle == true does not
display the directory content of an x64 app.

The parameter bVistaStyle == false works fine.

The same app as a Win32 app with portable-winehq-devel-5.0-osx.tar.gz works
fine.

It looks as if this issue is just on a Mac.

To demonstrate the issue please find demos in the attached zip file:

(1) Wine_Bug_CFileDialog_bVistaStyle_TRUE_x64.exe
This app shows the issue on portable-winehq-devel-5.0-osx64.tar.gz

(2) Wine_Bug_CFileDialog_bVistaStyle_FALSE_x64.exe
This app is fine and corretly shows the content on
portable-winehq-devel-5.0-osx64.tar.gz

(3) Wine_Bug_CFileDialog_bVistaStyle_TRUE_x86.exe
In contraty to (1) this runs fine on portable-winehq-devel-5.0-osx.tar.gz

(4) The demo app in source code as a Visual Studio project
