-DDK sdk for x86 and x64 platforms.
-----------------------------------
-
-You can check for existance of this optional package by verifying
-the definition of the macro MINGW_HAS_DDK_H.
-
-The DDK headers are from the ReactOS project, from their svn repo
-svn://svn.reactos.org/reactos/trunk/reactos/include/ddk/
-
-This is an optional SDK. Some of the headers are public domain and
-some of them are under LGPL license. You can obtain the original
-sources from the ReactOS project.
-
-How to install this SDK
-----------------------------------
-Please simply copy the content of the include directory within the
-include folder of our header-set. Most of the needed import libraries
-are already generated within the crt build, so you shouldn't need
-any further compilation.
