Queries to Windows MySQL servers from Linux Systems often fail unless
the lower_case_table_names parameter is set to 0 in the my.ini file in
the MySQL directory.
    

I'm familiar with that issue, and I checked all the table case-ness.  The 
problem seems to be with providing an empty string ('') as the value for an 
auto-incrementing integer primary index.
  

Yes that is true '' or empty strings are not nulls or integers... I suggest replacing the '' with the word null, this will sort out the issue based on the query you specified.

The problem with setting lower_case_table_names to 0 is that I could end up 
blowing away my MyISAM tables elsewhere in that server, as per the warning 
the service control gives, if I moof a query on those and use the "wrong" 
case:

  

I would rename the MyISAM tables using phpmyadmin or using SQL and sort out the Database to run case sensitive in the first place like the ANSI standard.

Or much better still mysqldump the entire MySQL server into a file "textfilename.sql", sort out the table names etc... using a good text editor, place a drop table if exists before each create table entry, save the file then run mysql -uroot -p < "textfilename.sql" to recreate all of the databases including data with tablenames in the correct case...

Maybe I am just too fussy...

"You have forced lower_case_table_names to 0 through a command-line option, 
even though your file system 'E:\MySQL\Data\' is case insensitive.  This 
means that you can corrupt a MyISAM table by accessing it with different 
cases. You should consider changing lower_case_table_names to 1 or 2"

  

Only if you live in an all windows world... "Compatability is a bitch it demands the use of standards, the little things which M$ don't adhere to very well" ;-)

It's working fine with my modifie query, so I'm just going to put this down 
to "a 5.x thing" and live with my change.  Compared to the wholesale hack 
and slash job I've had to do on the sqlippool queries to get them to work, 
it's no Big Whoop, LOL!

But thanks for the suggestion, I appreciate your time.
