1829 The time difference between 1 January 1601, 00:00:00 and
1830 1 January 1970, 00:00:00 is 369 years, plus the leap years
1831 from 1604 to 1968, excluding 1700, 1800, 1900.
1832 This makes (1968 - 1600) / 4 - 3 = 89 leap days, and a total
1835 Any day in that period had 24 * 60 * 60 = 86400 seconds.
1837 The time difference is 134774 * 86400 * 10000000, which can be written
1839 27111902 * 2^32 + 3577643008
1840 413 * 2^48 + 45534 * 2^32 + 54590 * 2^16 + 32768
1842 If you find that these constants are buggy, please change them in all
1843 instances in both conversion functions.
1846 There are two versions, one of them uses long long variables and
1847 is presumably faster but not ISO C. The other one uses standard C
1848 data types and operations but relies on the assumption that negative
1849 numbers are stored as 2's complement (-1 is 0xffff....). If this
1850 assumption is violated, dates before 1970 will not convert correctly.
1851 This should however work on any reasonable architecture where WINE
1856 Take care not to remove the casts. I have tested these functions
1857 (in both versions) for a lot of numbers. I would be interested in
1858 results on other compilers than GCC.
1860 The operations have been designed to account for the possibility
1861 of 64-bit time_t in future UNICES. Even the versions without
1862 internal long long numbers will work if time_t only is 64 bit.
1863 A 32-bit shift, which was necessary for that operation, turned out
1864 not to work correctly in GCC, besides giving the warning. So I
1865 used a double 16-bit shift instead. Numbers are in the ISO version
1866 represented by three limbs, the most significant with 32 bit, the
1867 other two with 16 bit each.
1869 As the modulo-operator % is not well-defined for negative numbers,
1870 negative divisors have been avoided in DOSFS_FileTimeToUnixTime.
1872 There might be quicker ways to do this in C. Certainly so in
