1611
1612        VERSIONS:
1613        There are two versions, one of them uses long long variables and
1614        is presumably faster but not ISO C. The other one uses standard C
1615        data types and operations but relies on the assumption that negative
1616        numbers are stored as 2's complement (-1 is 0xffff....). If this
1617        assumption is violated, dates before 1970 will not convert correctly.
1618        This should however work on any reasonable architecture where WINE
1619        will run.
1620
1621        DETAILS:
1622
1623        Take care not to remove the casts. I have tested these functions
1624        (in both versions) for a lot of numbers. I would be interested in
1625        results on other compilers than GCC.
1626
1627        The operations have been designed to account for the possibility
1628        of 64-bit time_t in future UNICES. Even the versions without
1629        internal long long numbers will work if time_t only is 64 bit.
1630        A 32-bit shift, which was necessary for that operation, turned out
1631        not to work correctly in GCC, besides giving the warning. So I
1632        used a double 16-bit shift instead. Numbers are in the ISO version
1633        represented by three limbs, the most significant with 32 bit, the
1634        other two with 16 bit each.
1635
1636        As the modulo-operator % is not well-defined for negative numbers,
1637        negative divisors have been avoided in DOSFS_FileTimeToUnixTime.
1638
1639        There might be quicker ways to do this in C. Certainly so in
1640        assembler.
