Description:
------------
mssql_select_db() doesnt let you select a database thats longer than 30 characters?

Reproduce code:
---------------
$Server = "server\\server,1433";
$User = "sa";
$Pass = "password";
$DB = "Thirty_Characters_or_more_db_name_here";

$s = mssql_connect("$Server", "$User", "$Pass");

$d = mssql_select_db("$DB", $s)or die("Couldn't open database $DB");

Expected result:
----------------
unable to select 'Thirty_Characters_or_more_db_na' from sysbase table...

Actual result:
--------------
same as above
