Added a comment to the abi_check related
part of configure.in

configure.in:
  Added a comment to the abi_check related
  part of configure.in

1) Disabled abi_check rule for all compilers except gcc
2) restored the -dI option to retain the header information.

Makefile.am:
  1) changed all-local to depend on a configure variable
     that will be set based on if the compiler is gcc.
  2) restored the -dI option removed earlier since now
     only gcc is being used.
configure.in:
  Added a check to see if gcc is being used. If it is being
  used set the ABI_CHECK variable to the abi_check target.
include/mysql.h.pp:
  The .pp file is changed to correspond to the option
  -dI.

1) Remove solaris sparc specific output produced by the
   pre-processor in the .out files
2) Ensure compatibility of preprocessor options for solaris/sparc
   platform.

Makefile.am:
  1) Added a sed regular expression to remove output produced
     by the preprocessor in the solaris sparc platform
  2) Removed the -dI option from the preprocessor to enable
     solaris/sparc compatibility
include/mysql.h.pp:
  Since the -dI option has been removed from the preprocessor
  the .pp files will correspondingly change.

mysql-test/suite/ndb/t/disabled.def:
  disabled failing test in 5.1-bzr
mysql-test/suite/rpl_ndb/t/disabled.def:
  disabled failing test in 5.1-bzr

fixed the abi_check rule to handle failure in the
diff command on the solaris platform.

Makefile.am:
  Removed the -B option from the diff command used
  on the abi_check rule.

sql/field.cc:
  Function is only used if replication is compiled in.

1) When gcc -E is run in the Mac OS it introduces a line of 
   output that results in showing up as a difference between 
   the .pp and .out files. Removed this OS specific preprocessor 
   text inserted by the preprocessor in the MAC OS. Added a sed 
   regular expression to remove MAC OS specific pre-processor
   text.

2) Added the -w option to diff to remove the differences in
   output being caused in solaris.

Makefile.am:
  1) When gcc -E is run in the Mac OS it introduces a line of

     the .pp and .out files. Removed this OS specific preprocessor

     regular expression to remove MAC OS specific pre-processor
     text.
  
  2) Added the -w option to diff to remove the differences in
     output being caused in solaris.

sql/log.cc:
  Auto merge

This does not fix the bug. It only disables the failing test.


mysql-test/suite/rpl/t/disabled.def:
  disable rpl_temporary

Modified the abi_check command to ignore space
differences between the .pp and the .out files.

Makefile.am:
  Modified the abi_check command to ignore space
  differences between the .pp and the .out files.

If the server failed to expired log files during start up it could crash.

sql/log.cc:
  Added predicate to protect againt cases when current_thd might be NULL.

use thread-local data structures in ha_release_temporary_latches()

1) Modified abi_check rule to not write into the
   distribution directory.
2) Added the .pp files to EXTRA_DIST so that it will
   be included in the distribution

Makefile.am:
  Modified the abi_check rule to not generate the
  .out files in the distribution directory.
include/Makefile.am:
  Added the EXTRA_DIST entry for plugin.h.pp and
  mysql.h.pp so that they will be included while
  creating the distribution.

      
the reason for the failure is that io thread passes through a sequence of state
changes before it eventually got stuck at the expect running state as NO.
It's unreasonble to wait for the running status while the whole idea of the test is
to get to the IO thread error.

Fixed with changing the waiting condition.

mysql-test/suite/rpl/r/rpl_server_id1.result:
  results changed
mysql-test/suite/rpl/t/disabled.def:
  re-enabling rpl_server_id1
mysql-test/suite/rpl/t/rpl_server_id1.test:
  deploying the exact waiting condition i.e to wait for the slave io error.

- Revert the fix for bug 33812
- fixed a win32 warning

client/mysql.cc:
  revert the fix for bug 33812
mysql-test/r/mysql.result:
  revert the fix for bug 33812
mysql-test/t/mysql_delimiter.sql:
  revert the fix for bug 33812
mysys/default.c:
  fixed a win32 warning

Problem: missing initialization, if the previous test
fails leaving table t1, client_xml fails as well.
Fix: adding initialization.
