TYPO3 Core

the $debugOutput flag which is false by default should be controllable by localconf.

Reason:

In many situations typo3 and t3lib are symbolic links on a host not accesible by the poor devil how has to debug something in a customer installation.

If a sql error occurs like :

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'tt_news.t3ver_id,tt_news.t3ver_state,tt_news.t3ver_wsid,tt_news.t3ver_count,tt_n' at line 1 like a customer of mine has in tt_news

you as a consultant has no change to find out what is the complete sql query. The sql fragment given by mysql_error gives no clue what could be possible wrong.

In my case I am not able to debug the core because its an symbolic link for that link I do not have access with ftp. I am not able to set the flag true.
