title: GNAT-GPS 2015 and cygwin.S issue
body: <p>I am running an Ada project in GPS-GNAT 2015 that has a C++ User Interface and when debugging I reach the point where I attempt to send data from Ada to the C++ window however I am receiving an error:</p>
  
  <blockquote>
    <p>__chkstk_ms () ../../../src/libgcc/config/i386/cygwin.S 168 no such file or directory found.</p>
  </blockquote>
  
  <p>Any help would be greatly appreciated. Thanks  &nbsp;</p>
