    GDate test: Disable Julian epoch test on Windows
    
    Windows uses FILETIME, which starts counting from 1st Jan of year 1601 and,
    unlike time_t, can't be negative, so Windows simply has no way
    to do timestamp-math for dates before then. SYSTEMTIME (an equivalent
    of struct tm) can, obviously, represent almost arbitrary date starting
    from 1st Jan of year 0 (it's unsigned...), but GetDateFormatW() converts it
    to FILETIME at some point in its implementation, and fails.
    Unless the whole strftime() implementation of GDate is replaced by
    something that doesn't rely on WinAPI, this part of the test will
    never pass.
