title: how to get rid of "In class initializer for static data member ... is a C++0x extension" warning in Xcode 4
body: <p>I can get rid of the warnings in the build log by adding -std=c++0x to "other c++ flags", but they still show up in the side pane.  I'm guessing that the other flags are not being passed to clang or whatever is responsible for parsing code for the gui...</p>
  
  <p>Any ideas?</p>
  
  <p>Update:</p>
  
  <p>The warnings have mostly disappeared, but I'm not sure why.  And every time I think they're gone, I get a few again.  I suspect that forcing a build of every project in the workspace has some effect, but I'm really at a loss.</p>
  
  <p>In any case, modifying "other c++ flags" does seem to affect the GUI warnings, contrary to my assumption when I asked this question.  But it takes time.  Ahh, Xcode.</p>
