_wfindfirst64i32() and _wfindnext64i32() first appeared in MSVCR80.DLL,
and to this day, are firmly associated with this non-free MSVC DLL, and
its descendants; they have never, at least up to Win7, never been added
to the system-standard MSVCRT.DLL, upon which MinGW relies[*].

If you want your application to work with a standard MinGW setup, then
you should not be explicitly referring to this, (or to any other
variant), of _wfindnext(); you should use the generic form.  Also, you
need to be aware that, in MSVCRT.DLL, the generic form continues to use
the __time32_t representation of time_t, (irrespective of the insanity
of _USE_32BIT_TIME_T), whereas _wfindnext64i32() uses the __time64_t
representation, (coupled with 32-bit file size).

[*] Sure, it is *possible* to configure MinGW to work with MSVCR80.DLL
and its later derivatives, but I am not going to encourage it.
