title: G++ enable -fexceptions
body: <p>i have created a C++ project for my STM32 using eclipse (SW4STM32, which is basicly eclipse CDT).
  However I'm not able to set the exception flag. </p>
  
  <pre><code>error: exception handling disabled, use -fexceptions to enable
  </code></pre>
  
  <p>I searched the g++ compiler options but i could not find an option here. So I tried to add this flag as miscellaneous but no lock there :(
  Could you give me a hint please?</p>
