Has anyone else had trouble compiling winsamp.d in the samples directory?

Here is the error I get when I issue the "dmd winsamp.d" command:

winsamp.d(8): identifier 'WPARAM' is not defined

Thanks for any suggestions,
Kennedy

PS.
The file winsamp.d I'm using is unmodified from the samples supplied with
the compiler. But just in case, here it is:

   }

  }
 } break;

It doesn't build. D doesn't have a complete Windows definition file yet. I have gotten it to build by bringing in Pavel's windows.d file which you can find in the links section of the D site.

You need to compile Pavel's windows.d with your program.
