Replacing AC_CHECK_FUNC+AC_CHECK_LIB combination with
AC_SEARCH_LIBS.

returns short string value. 
 
Multibyte character sets were not taken into account when 
calculating max_length in Item_param::convert_str_value(). As a 
result, string parameters of a prepared statement could be 
truncated later when calculating string length in characters by 
dividing length in bytes by the charset's mbmaxlen value (e.g. in 
Field_varstring::store()). 
 
Fixed by taking charset's mbmaxlen into account when calculating 
max_length in Item_param::convert_str_value().


sql/item.cc:
  Multiply string's length in characters by charset's mbmaxlen when 
  calculating max_length.
tests/mysql_client_test.c:
  Added a test case for bug #41078.

      
Removed the misleading "NOTE:" from the \h command. 

client/mysql.cc:
  Bug #26724: removed the misleading note from the \h command

stack reservation too small

Problem: some tests fail on HP-UX due to insufficient stack reservation.

Fix: increase stack reservation.


sql/mysql_priv.h:
  Fix for bug#21476: stack overflow crashes server; error-message
  stack reservation too small
    - raised STACK_MIN_SIZE to pass execution_constants.test on HP-UX.

Cleaned up SQL code in the test.
Needed to move the FLUSH TABLES statement prior to the DROP TABLE t1 to prevent a warning of
Table open on delete and a test fail.

Dirty close tricky does not work on Windows.

mysql-test/r/query_cache_notembedded.result:
  Remove test case result.
mysql-test/t/query_cache_notembedded.test:
  Remove test case.
