2182 CONSTANTS:
2183 The time difference between 1 January 1601, 00:00:00 and
2184 1 January 1970, 00:00:00 is 369 years, plus the leap years
2185 from 1604 to 1968, excluding 1700, 1800, 1900.
2186 This makes (1968 - 1600) / 4 - 3 = 89 leap days, and a total
2187 of 134774 days.
2188
2189 Any day in that period had 24 * 60 * 60 = 86400 seconds.
2190
2191 The time difference is 134774 * 86400 * 10000000, which can be written
2192 116444736000000000
2193 27111902 * 2^32 + 3577643008
2194 413 * 2^48 + 45534 * 2^32 + 54590 * 2^16 + 32768
2195
2196 If you find that these constants are buggy, please change them in all
2197 instances in both conversion functions.
2198
2199 VERSIONS:
2200 There are two versions, one of them uses long long variables and
2201 is presumably faster but not ISO C. The other one uses standard C
2202 data types and operations but relies on the assumption that negative
2203 numbers are stored as 2's complement (-1 is 0xffff....). If this
2204 assumption is violated, dates before 1970 will not convert correctly.
2205 This should however work on any reasonable architecture where WINE
2206 will run.
2207
2208 DETAILS:
2209
2210 Take care not to remove the casts. I have tested these functions
2211 (in both versions) for a lot of numbers. I would be interested in
2212 results on other compilers than GCC.
2213
2214 The operations have been designed to account for the possibility
2215 of 64-bit time_t in future UNICES. Even the versions without
2216 internal long long numbers will work if time_t only is 64 bit.
2217 A 32-bit shift, which was necessary for that operation, turned out
2218 not to work correctly in GCC, besides giving the warning. So I
2219 used a double 16-bit shift instead. Numbers are in the ISO version
2220 represented by three limbs, the most significant with 32 bit, the
2221 other two with 16 bit each.
2222
2223 As the modulo-operator % is not well-defined for negative numbers,
2224 negative divisors have been avoided in DOSFS_FileTimeToUnixTime.
2225
2226 There might be quicker ways to do this in C. Certainly so in
2227 assembler.
