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