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.
