- BIGENDIAN-> ARCH_BIGENDIAN .
BIGENDIAN constant is defined in winsock2.h (as 0)
- added explicit cast for longlong->double conversion in sql/item.h (fixed many warnings)
Also, HAVE_SNPRINTF is now defined and snprintf is defined to _snprintf in config-win.h
and collateral changes.

Bug #55755 : Date STD variable signness breaks server on FreeBSD and OpenBSD
* Added a check to configure on the size of time_t
* Created a macro to check for a valid time_t that is safe to use with datetime
functions and store in TIMESTAMP columns.
* Used the macro consistently instead of the ad-hoc checks introduced by 52315
* Fixed compliation warnings on platforms where the size of time_t is smaller than
the size of a long (e.g. OpenBSD 4.8 64 amd64).
Bug #52315: utc_date() crashes when system time > year 2037
* Added a correct check for the timestamp range instead of just variable size check to
SET TIMESTAMP.
* Added overflow checking before converting to time_t.
* Using a correct localized error message in this case instead of the generic error.
* Added a test suite.
* fixed the checks so that they check for unsigned time_t as well. Used the checks
consistently across the source code.
* fixed the original test case to expect the new error code.
MySQL officially supports DATE values starting from 1000-01-01. This is
enforced for int values, but not for string values, thus one
could easily insert '0001-01-01' value. Int values are checked by
number_to_datetime function and Item_cache_datetime::val_str uses it
to fill MYSQL_TIME struct out of cached int value. This leads to the
scenario where Item_cache_datetime caches a non-null datetime value and when
it tries to convert it from int to string number_to_datetime function
treats the value as out-of-range and returns an error and
Item_cache_datetime::val_str returns NULL for a non-null value. Due to this
inconsistency server crashes.
Now number_to_datetime allows DATE values below 1000-01-01 if the
TIME_FUZZY_DATE flag is set. Better NULL handling for Item_cache_datetime.
Added the Item_cache_datetime::store function to reset str_value_cached flag
when an item is stored.
mysql-test/r/type_date.result:
Added a test case for the bug#57278.

TIME_FUZZY_DATE flag is set.
sql/item.cc:
Bug#57278: Crash on min/max + with date out of range.
Item_cache_datetime::val_str now better handles
null_value.
Although the C standard mandates that sprintf return the number
of bytes written, some very ancient systems (i.e. SunOS 4)
returned a pointer to the buffer instead. Since these systems
are not supported anymore and are hopefully long dead by now,
simply remove the portability wrapper that dealt with this
discrepancy. The autoconf check was causing trouble with GCC.

bugfix: fix @@wait_timeout to work with socket timeouts (vs. alarm thread)
with gcc 4.3.2
This patch fixes a number of GCC warnings about variables used
before initialized. A new macro UNINIT_VAR() is introduced for
use in the variable declaration, and LINT_INIT() usage will be
gradually deprecated. (A workaround is used for g++, pending a
patch for a g++ bug.)
GCC warnings for unused results (attribute warn_unused_result)
for a number of system calls (present at least in later
Ubuntus, where the usual void cast trick doesn't work) are
also fixed.
client/mysqlmanager-pwgen.c:
A fix for warn_unused_result, adding fallback to use of
srand()/rand() if /dev/random cannot be used. Also actually
adds calls to rand() in the second branch so that it actually
creates a random password.
There were a problem since pruning uses the field
for comparison (while evaluate_join_record uses longlong),
resulting in pruning failures when comparing DATE to DATETIME.
Fix was to always comparing DATE vs DATETIME as DATETIME,
by adding ' 00:00:00' to the DATE string.
And adding optimization for comparing with 23:59:59, so that
DATETIME_col > '2001-02-03 23:59:59' ->
TO_DAYS(DATETIME_col) > TO_DAYS('2001-02-03 23:59:59') instead
of '>='.

Bug#38435 - LONG Microseconds cause MySQL to fail a CAST to DATETIME or DATE
Parsing of optional microsecond part in datetime did not
fail gracefully when field width was larger than the allowed
six places.
Now handles up to the correct six places, and disregards
any extra digits without messing up what we've already got.
mysql-test/r/type_datetime.result:
show graceful handling of overly long microsecond parts
(correct truncation).
mysql-test/t/type_datetime.test:
show graceful handling of overly long microsecond parts
(correct truncation).
sql-common/my_time.c:
Special case for time-parsing: for microsecond part,
leading zeroes are actually meaningful! Also, don't
break the entire date on more than the allowed six
digits in microsecond part, just truncate the extra
digits.
Passing dubious "year zero" in non-zero date (not "0000-00-00") could
lead to negative value for year internally, while variable was unsigned.
This led to Really Bad Things further down the line.
Now doing calculations with signed type for year internally.
mysql-test/r/date_formats.result:
show that very early dates no longer break DATE_FORMAT(..., '%W')
mysql-test/t/date_formats.test:
show that very early dates no longer break DATE_FORMAT(..., '%W')
sql-common/my_time.c:
Allow negative years numbers internally while keeping the interface.
otherwise if somebody passes year zero for whatever reason, we'll
get an integer wrap-around that can lead to Really Bad Things further
down the line. Note that amusingly, calcday_nr() already had signed
output and calc_weekday() already had signed input, anyway.

This is a regression from 2007-05-18 when code to zero out the returned struct was
added to number_to_datetime(); zero for time_type corresponds to MYSQL_TIMESTAMP_DATE.

BETWEEN was more lenient with regard to what it accepted as a DATE/DATETIME
in comparisons than greater-than and less-than were. ChangeSet makes < >
comparisons similarly robust with regard to trailing garbage (" GMT-1")
and "missing" leading zeros. Now all three comparators behave similarly
in that they throw a warning for "junk" at the end of the data, but then
proceed anyway if possible. Before < > fell back on a string- (rather than
date-) comparison when a warning-condition was raised in the string-to-date
conversion. Now the fallback only happens on actual errors, while warning-
conditions still result in a warning being to delivered to the client.
mysql-test/r/select.result:
Show that we compare DATE/DATETIME-like strings as date(time)s
now, rather than as bin-strings.
Adjust older result as "2005-09-3a" is now correctly seen as
"2005-09-3" + trailing garbage, rather than as "2005-09-30".

now, rather than as bin-strings.

warning for at that. Preamble doxygenized.
