Description:
------------
When using mysql_connect with host:port parameter, with port other than 3306, the connection times out.
Am able to telnet to the DB host on the alternative port, with mysql responding as expected.

Tried using latest snapshot, as well as 5.2.5

Reproduce code:
---------------
<?
if( mysql_connect('192.168.151.116:3306','foo','**********') ) {
  print "3306 connected OK\n";
} else {
  print "3306 failed connect\n";
}
if( mysql_connect('192.168.151.116:3307','foo','**********') ) {
  print "3307 connected OK\n";
} else {
  print "3307 failed connect\n";
}
?>


Expected result:
----------------
3306 connected OK
3307 connected OK

Actual result:
--------------
[root@dopey default]# /root/newphp/php5.2-200803181530/sapi/cli/php test.php
3306 connected OK
