Check for existence of diff fails on Solaris due to unsupported "-v"
Fix is to do this check only on Windows where it was needed

packages, this is now corrected (Bug#42278)

This is not the final merge of that release build, but we need early
access to these tool fixes (use of "awk" in the BDB configuration).

The default "awk" there cannot handle some of the scripts
which are used by BDB for configuration.

The fix:
1) Introduce a variable "AWK" in some of the BDB shell scripts,
2) search "gawk" and give it precedence over "awk"
   when assigning a value to the "AWK" variable,
   fail if neither is found,
3) use that variable when calling an "awk" program with one
   of the critical scripts.

The perfect solution would be to use the "awk" program found
by "configure", but we cannot follow that approach because
BDB's configuration is handled as a special case before the
overall "configure" is run. Because of this,
1) the "configure" result isn't yet available,
2) "configure" will not handle these BDB files.
Searching "gawk" is a (not-so-nice) way out.

Note that all this need not be perfectly portable,
it is needed only when we create a source distribution tarball
from a develkopment tree.

bdb/dist/s_all:
  Search "gawk" if available, give it precedence over "awk",
  fail if neither is found.
bdb/dist/s_include:
  Ensure we use a modern AWK, similar to GNU awk,
  the default awk on Solaris cannot handle BDB's script.
bdb/dist/s_recover:
  Ensure we use a modern AWK, similar to GNU awk,
  the default awk on Solaris cannot handle BDB's script.
bdb/dist/s_rpc:
  Ensure we use a modern AWK, similar to GNU awk,
  the default awk on Solaris cannot handle BDB's script.

Bug #39920: MySQL cannot deal with Leap Second expression in string literal.

Updated MySQL time handling code to react correctly on UTC leap second additions.
MySQL functions that return the OS current time, like e.g. CURDATE(), NOW() etc
will return :59:59 instead of :59:60 or 59:61.
As a result the reader will receive :59:59 for 2 or 3 consecutive seconds
during the leap second.

When substituting system constant functions with a constant result

Passing dubious "year zero" in non-zero date (not "0000-00-00") could

  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

  output and calc_weekday() already had signed input, anyway.

The problem is that we cannot insert new record into memory table
when table size exceeds max memory table size.
The fix is to use schema_table_store_record() function which
converts memory table into MyISAM in case of table size exceeding.

Note:
There is no test case for this bug, the reason is that
1. The code  that was added already is checked(i.e. works) with existing tests
2. Correct work of schema_table_store_record() is checked with other test cases
   (information_schema tests)
So new code is fully covered with existing test cases.

- QUICK_INDEX_MERGE_SELECT deinitializes its rnd_pos() scan when it reaches EOF, but we 
  need to make the deinitialization in QUICK_INDEX_MERGE_SELECT destructor also. This is because
  certain execution strategies can stop scanning without reaching EOF, then then try to do a full
  table scan on this table. Failure to deinitialize caused the full scan to use (already empty) 
  table->sort and produce zero records.

Fix Bug#36149 Read buffer overflow in srv0start.c found during "make test"

Use strncmp(3) instead of memcmp(3) to avoid reading past end of the string
if it is empty (*str == '\0'). This bug is _not_ a buffer overflow.

Fix of issue# 4

Fixed a timing hole where a thread dropping an index can free the
in-memory index struct while another thread is still using
that structure to remove entries from adaptive hash index belonging
to one of the pages that belongs to the index being dropped.

The fix is to have a reference counter in the index struct and to
wait for this counter to drop to zero beforing freeing the struct.
