Schema upgrade fails in 3.2.1 when using SQL Server

When running the current 3.2 code on SQL Server, and attempting to do schema upgrades during an update, the upgrade process fails silently with no error message - it just stops.

Investigating error logs, I found in /phpbb/db/tools/mssql.php two references that are incorrect, and cause schema changes to fail. 

Lines 524 and 544 contain this code:

if ($this->is_sql_server_2000())

The code should be:

if ($this->mssql_is_sql_server_2000())
