The cause of the bug is that Item_func_in::fix_fields did not fully update its
used_table_cache. This was the cause for not_null_tables in setup_conds() to be
still 0 after the call
not_null_tables= (*conds)->not_null_tables();
As a result the condition in setup_conds()
if ( ... (table->table->map & not_null_tables) ...)
failed, which was the cause for the ON expression not to be added to conds, and later
the optimizer couldn't detect that it could apply the OUTER JOIN ==> JOIN optimization.

mysql_priv.h, my_time.h:
Moved declaration of days_in_month array from mysql_priv.h to my_time.h to correct Windows build issues
Added declarations for print_msg_to_log and vprint_msg_to_log. sql_print_error are simple functions that wrap calls to print_msg_to_log. Define the different error types with MY_ERROR_TYPE, MY_WARNING_TYPE, and MY_INFORMATION_TYPE
gen_lex_hash.cc:
Added NULL error reporting parameter to handle_options
log.cc:
Add print_msg_to_log, print_buffer_to_log, and vprint_msg_to_log. Print_msg_to_log will write the message to the windows event log if on NT. We now have error, warning, and information versions of sql_print_xxxx. T his is a variation of a similar changeset WAX did.
mysqld.cc:
Added option_error_reporter callback function and pass that into handle_options
mysql.cc:
Added NULL as error reporter arg to the end of handle_options
Many files:
Added NULL error reporter parameter as the last paramter to handle_options
my_getopt.c:
Added second function pointer to server as an error reporting callback. Added local function report_option_error that will either write the error to stderr or to the error reporting callback. changed all calls in handle_options from fprintf(stderr, ... ) to report_option_error
my_getopt.h:
Changed declaration of handle_options to use typedefs for the two function pointers. added second function pointer to server as an error reporting callback
mysqld.dsp:
Added custom build step for compiling message file and added message resource file (output of mc)
next-key locking. Using this option the locks InnoDB sets on index
records do not affect the ``gap'' before that index record. Thus, this option
allows phantom problem.

Do-compile:
1. Option to ensure that logs are moved and then backed up on each host prior to a build
2. Option to run build with flag "--without-ndbcluster"
