Summary: Braces without a purpose

Initial Comment:
TimRiker has been having problems compiling with my 
radar changes, and while I've been going through his 
debugging dumps I've found an oddity that could be 
causing trouble:

I've found a pair of curly braces {} that seem to 
seperate a block of code, but do not have an 
associated statement:


  {
    int n = 3;	// assume triple buffering
    switch (sceneRenderer->getViewType()) {
      case SceneRenderer::Stacked:
      case SceneRenderer::Stereo:
#ifndef USE_GL_STEREO
	// control panel drawn twice per frame
	n *= 2;
#endif
	break;

      case SceneRenderer::ThreeChannel:
      default:
	// only one copy of control panel visible
	break;
    }
    controlPanel->setNumberOfFrameBuffers(n);
  }

This is very weird indeed.  No if, no loop, no 
anything.  Since this problem has been in the code 
before my radar changes, I'll continue looking through 
the debug dump to make sure there aren't any more 
problems.

In the file playing.cxx, in the "startPlaying" 
function.  Line 4328 according to VC++ (although VC++ 
and GDB don't seem to agree on line numbering).

Thanks.  The problem wasn't the braces anyway.

This is perfectly normal, it just provides limited scoping 
for variable n.
