title: g++: unrecognized option '-static-libstdc++'
body: <p>I'm trying to link DLL with the following command:
  <code>g++ -DFTCSPI_EXPORTS -shared -fpic -static-libgcc -static-libstdc++ tmp\*.o "%D2XX_Dir%\ftcspi.lib" "%TclLibFile%" -o tmp\ftcspiif.dll</code></p>
  
  <p>I'm getting this error: <code>g++: unrecognized option '-static-libstdc++'</code></p>
  
  <p>I've checked I have libstdc++-6.dll in C:\MinGW\bin and my gcc version is 4.4.7.</p>
  
  <p>Does anyone have any ideas what might be going on?  Thanks in advance.</p>
