Subject: [PATCH] This will hopefully solve the src/src problem. I am a bit
 concerned about auth.php, since it's in functions and is, therefore,
 included. $PHP_SELF can be anything in it.

git-svn-id: https://svn.code.sf.net/p/squirrelmail/code/trunk/squirrelmail@2689 7612ce4b-ef26-0410-bec9-ea0150e637f0
