The problem is porting older source from mingw32-w32 (older 32 bit 
toolchain) and make it able to build for 64 bit now, and a wish to use 
the same source for 32 bit again. Under 32 bit the ntddscsi.h exist only 
under .../include/ddk/ntddscsi.h, and now it exist under 
.../include/ntddscsi.h

Under mingw32-w32 have not set extra path for ddk-headers, and must use 
includes for kernel driver in such way:

   #include <ddk/ntddscsi.h>

For mingw32-w64 I must add include path for ddk headers to gcc options 
and must remove diretory "ddk/" from include statement:

   #include <ntddscsi.h>

As result I have such code lines now:

   #include <ddk/ntddk.h>
   #ifndef WIN64
     #include <ddk/ntapi.h>
   #endif
   #include <ddk/ntifs.h>
   #include <ddk/ntdddisk.h>
   #ifdef WIN64
     #include <ntddscsi.h>
   #else
     #include <ddk/ntddscsi.h>
   #endif
