You need at least Digital Mars C++ 8.32.14 (earlier versions won't
work).

Some notes about compiling with DM:

 * Use "platform = x86_win32_dmc" in config\config.mak

 * x86_win32_dmc.mk uses "-ND" to link with DM's DLL runtime library
   (which isn't included in the download version of the compiler), if
   you want to link with the static version of the runtime library you
   have to replace "-ND" with "-D_MT".

 * You can use the Python DLL included in Python binary distributions,
   but you have to create a Python import library for DM using "implib
   /system python22.lib python22.dll" and copy the import library to
   src\tool\omniidl\cxx\

 * I am using the MSYS (see http://www.mingw.org/msys.shtml) versions
   of the GNU tools - for using the Cygwin tools or some other Win32
   port of the GNU tools, minor changes to x86_win32_dmc.mk might be
   necessary. In particular, DM's "link" and "lib" commands can't be
   directly invoked from MSYS's make/sh, therefore these commands are
   indirectly invoked via "cmd //c" (if that doesn't work for you, you
   can try replacing it with "cmd /c" or completely removing the "cmd
   //c" part).

 * DM's link sometimes complains about unknown "libpath" options
   (these can safely be ignored) - the build system currently assumes
   that MSVC++ is used on Windows

 * I get an "out of memory" error when trying to compile
   src\services\mklib\CosNotifyChannelAdminSK.cc with debug
   information

 * I haven't done much testing yet (omniNames does at least start up)
