title: G++ fails to compile Win7, 64bit (MinGW.org GCC-6.3.0-1)
body: <p>G++ fails to compile simple "Hello World" code.
  Platform details are in the Title
  I have tried to run from both VS Code ("insiders" version 1.26.0), and from the Windows command-line /terminal.
  Neither route will return an *.exe file
  This is the C++ code. VSCode Intellisense doesn't show any errors (C++17)</p>
  
  <pre><code>#include &lt;iostream&gt;
  using namespace std;
  int main()
  {
      std::cout &lt;&lt; "Fresh New World" &lt;&lt; std::endl;
      return 0;
  }
  </code></pre>
  
  <p>At the Windows command line (terminal) I've used the command</p>
  
  <pre><code>g++ -o FreshWorld.exe FreshWorld.cpp
  </code></pre>
  
  <p>This command does <strong>not</strong> return an error, nor does it return the desired *.exe file (I've even resorted to SEARCHing all the folders)
  Running this in VSCode (1.26.0) also does not return an error.
  I had run this code in the previous stable release (pre- "June 2018") VS Code, and it compiled properly. The problems started immediately after the update to Jn2018. I've worked with VS Code developers (that's why I'm running the "insiders" version) but, as we now know, the problem also exists at the command-line (terminal) so not confined to VS Code.
  Any ideas??????
  I am entire newbie to C++, MinGW, and to VS Code so this has become an insurmountable hurdle to further experimentation and learning!</p>
