Just a small patch for the date_time library. WinCE does not supply the GetSystemTimeAsFileTime Win32 method. It does however supply the individual GetSystemTime and SystemTimeToFileTime methods. The config headers already define BOOST_NO_GETSYSTEMTIMEASFILETIME to flag this situation and the patch uses this define to mark when the alternate function calls should be substituted.
