Do you think that's the right behaviour? (from your code)
// get pixelformat
FillChar(pfd,SizeOf(pfd),0);
with pfd do begin
    nSize:=sizeOf(pfd);
    nVersion:=1;
    dwFlags:=PFD_DRAW_TO_WINDOW or PFD_SUPPORT_OPENGL;
    if DoubleBuffered then
      dwFlags:=dwFlags or PFD_DOUBLEBUFFER;
    if RGBA then
      dwFlags:=dwFlags or PFD_TYPE_RGBA;
    iPixelType:=24; // color depth -> this isn't the color! This has to be
iPixelType:=PFD_TYPE_RGBA, the color is cColorBits:=24;
    cDepthBits:=16; // Z-Buffer
    iLayerType:=PFD_MAIN_PLANE;
  end;

But the question is, why does this work on windows (doesn't it?) and not on
wine! Probably there are some test cases needed.
