Description:
------------
I have tried to use the crypt function using a 1 char length salt in different servers and the output went different.

When I use a 2 char length salt, the output is the same.

The architecture of the servers who gave the different output is 32 bits, i think this could be a hint.

Reproduce code:
---------------
<?php
echo  CRYPT_STD_DES . CRYPT_EXT_DES . CRYPT_MD5. CRYPT_BLOWFISH."<br>";
echo crypt('1234','Z');
?>

Expected result:
----------------
Linux (several distributions) 64 bits:
1010
Z$pzJXrYhCQNg

Actual result:
--------------
Windows 32bit:
1010
Z$qZF7.jfwpCE

Debian 5 32 bits:
1111
Z$qZF7.jfwpCE
