Description:
------------
Looking at ext/mysql/config.m4, it seems to me that the path specified during the ./configure step using the --with-mysql-sock option gets ignored and PHP_MYSQL_UNIX_SOCK_ADDR isn't defined accordingly. This causes mysqlnd to always use its default socket path (/tmp/mysql.sock).

I wrote a patch [1] to move the related code in its own if clause so that it gets executed regardless of whether mysqlnd or libmysqlclient is used. However, I was unable to test it because I'm not sure how to regenerate the configure script (I tried with autoreconf but the produced configure script freaked out; something about confdefs.h missing).

Let me know if you need any more information from me.

Tried with the snapshot; same problem.

 [foutrelis@foutboxd php]$ php -r 'mysql_connect();'
 PHP Warning:  mysql_connect(): [2002] No such file or directory (trying to connect via unix:///tmp/mysql.sock) in Command line code on line 1

The pdo_mysql extension is affected as well. When mysqlnd is enabled, PDO_MYSQL_UNIX_ADDR doesn't get defined and it uses /tmp/mysql.sock instead of the path retrieved using `mysql_config --socket'.

In this case, the code in ext/pdo_mysql/config.m4 is a bit more involved, so I won't attempt to come up with a patch. :>

Fixed both ext/pdo_mysql and ext/mysql, hopefully it works now. :)
