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:


import windows;
import c.stdio;

const int IDC_BTNCLICK = 101;
const int IDC_BTNDONTCLICK = 102;

extern(Windows)
int WindowProc(HWND hWnd, uint uMsg, WPARAM wParam, LPARAM lParam)
{
 switch (uMsg)
 {
 case WM_COMMAND:
 {
  switch (LOWORD(wParam))
  {
  case IDC_BTNCLICK:
   if (HIWORD(wParam) == BN_CLICKED)
    MessageBoxA(hWnd, "Hello, world!", "Greeting",
     MB_OK | MB_ICONINFORMATION);
   break;
  case IDC_BTNDONTCLICK:
   if (HIWORD(wParam) == BN_CLICKED)
   {
    MessageBoxA(hWnd, "You've been warned...", "Prepare to die!",
     MB_OK | MB_ICONEXCLAMATION);
    *(cast(int*) null) = 666;
   }
   break;
  }
 } break;

  SetTextAlign(dc, TA_CENTER | TA_BASELINE);
  TextOutA(dc, r.right / 2, r.bottom / 2, text, text.length);
  SelectObject(dc, old);
  EndPaint(hWnd, &ps);

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.

I downloaded Pavel's windows.d & the WPARAM error is gone but now I get a slew of "Symbol Undefined" errors on _CreateFontA@56, _SelectObject@8, ...

Any ideas?

Thanks.

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