Joins on indexed columns does not work on Linux.
The error is "table doesn't exist"

works correctly.

ERROR 1146: Table 'test.MSG' doesn't exist

This is a critical error, because all columns in joins usually indexed and thus joins are disabled on Linux.

How to repeat:
create table test (id int);
create table test1 (id int);
create unique index test_idx on test (id);
create unique index test1_idx on test1 (id);
select test.id from TEST join TEST1 on (test.id=test1.id);

You will receive an error:
ERROR 1146: Table 'test.TEST' doesn't exist

Suggested fix:
please, solve it and rebuld distribution on download area if possible.

and just to clarify - table names are case-sensitive on Linux

very sorry - you are right!
will check a cases more tightly in the future

Additional info:
only JOIN on indexed columns is a "case-sensitive", another statements is not case sensitive.

It is impossible to transfere a database from Windows to Linux, because it is impossible to create a table in upper case using CREATE TABLE `TEST` - it is created in lowercase. If i rename a file on disk, mysqldump always uses lower case for CREATE TABLE clause.
