Visual Studio 2015 compiled Versus MinGW cross-compiled code?

 Okay,  I decided to build my Visual Studio 2015 test application using mingw in Ubuntu as a separate project.    When I did this, the test successfully showed the problem when run in Wine, whereas with Windows it worked fine.    This means that with NT version 4 the problem also arises.  
I don't know exactly what accounts for the difference between that and the test as I set it up in dlls/comctl32/tests/combo.c.      That's what I'll look into now.

When I change the MajorOperatingSystemVersion field in the PE files (I mistakenly referred to MajorSubsystemVersion above) for both the wine cross compiled and the Windows Visual Studio 2015 version, the performance of neither changed.
Also, I realized that the version of mingw does default to 4. I read the wrong field.
I'm pursuing another approach now.

Does this cause the behavior difference you see? If you edit the header
manually, does the mingw build get the msvc behavior and vice versa?
