Bug #15606 MySQL5 reports unknown column XXX in 'on clause' when column exists

Description:
Running the following query on MySQL 5.0.16 produces the error "Error #1054: Unknown column 's.id' in 'on clause'"

SELECT 1 FROM student s, slp_calendar scal, subject LEFT JOIN slp_commentary sc ON sc.sid=s.id LIMIT 1;

But on MySQL 4.1.15-standard-log using an identical table structure, the query executes correctly.

If slp_calendar and subject are removed from the query, it executes correctly on 5.0.16:

SELECT 1 FROM student s  LEFT JOIN slp_commentary sc ON sc.sid=s.id LIMIT 1;

--> 1

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.mysql.com/documentation/ and the instructions on
how to report a bug at http://bugs.mysql.com/how-to-report.php

Additional info:

Please see the Manual about the join syntax, from version 5.0.12 that behavior
was changed, see the release changes notes for that version.
