-Disable a warning about lack of polymorphic type support for the following reasons
-- the only reason to have library block in the file is to make midl accept coclass
-  statement and generate CLSID for CActiveIMM.
-- the generated dimm_i.c has the clsid and that file is used to have clsid available
-- the dimm.tlb is not used at all
-- on top of it, there is no plans to port the app using dimm.idl to 64b platform.

- * DESCRIPTION:
- * This module produces Global IME for Vim, on Windows with Internet
- * Explorer 5.01 or higher.  You need three files "dimm.idl", "dimm.h", and
- * "dimm_i.c" when compile this module at your self.  "dimm.h", and
- * "dimm_i.c" are generated from "dimm.idl" by using MIDL.EXE as like
- * "if_ole.h".  You can get "dimm.idl" in MSDN web site.  I got it below
- * URL.
- *
- * WHAT IS THE GLOBAL IME?:
- * Global IME makes capability input Chinese, Japanese, and Korean text into
- * Vim buffer on any language version of Windows 98, Windows 95, and Windows
- * NT 4.0.  See below URL for detail of Global IME.  You can also find
- * various language version of Global IME at same place.
- *
- * RUNTIME REQUIREMENTS:
- * - Internet Explorer 5.01 or higher.
- * - Global IME (with language pack?).
- * - Of course Vim for Windows.
- *
- * URLS:
- * - Where you can probably get "dimm.idl".
- * http://msdn.microsoft.com/downloads/samples/internet/libraries/ie5_lib/sample.asp
- * - Global IME detailed information.
- * http://www.microsoft.com/windows/ie/features/ime.asp
