Can you print out the value to be sure?  I can't imagine they'd set it
lower themselves or make it go backwards in an upgrade, but perhaps
it's somehow not being set at all, and then we do:

#if defined(_MSC_VER) && _MSC_VER >= 1900
#define MIN_WINNT 0x0600
#else
#define MIN_WINNT 0x0501
#endif

In 16 we don't do that anymore, we just always set it to 0x0A00
(commit 495ed0ef2d72).  And before 15, we didn't want that function
yet (commit c1932e542863).
