Description:
------------
"pecl-5.1.6-Win32.zip" is missing some important modules. There are actually 4 modules that I decided I needed when I installed  the Apache 2.0.55 server and PHP 5.1.6 several months ago, though I haven't had reason to use a couple yet.

However, these are definitely needed:
 * MYSQL
 * MYSQLI
 * GD2
 * IMAP
Indeed, trying to connect to MySQL without having MYSQL or MYSQLI loaded results in "mysql_connect() undefined" errors (or mysqli_connect(), respectively!

Reproduce code:
---------------
if (!($connection = mysql_connect($hostname,$database,$username,$password))) {
     SOME-ERROR-HANDLING-STUFF-HERE;
     }
else echo "<p>Connection successful!<\p>\n\n";

Expected result:
----------------
I expect to see a message that the connection was successful

Actual result:
--------------
Instead I was getting "mysql_connect() undefined" errors.

(Copying the old module from PECL 5.1.2 into the "ext" directory solves the problem.)

But I shouldn't have to mix PECL versions, should I? Database functionality is not exactly a marginal requirement -- PECL 5.1.6 should have it.
