Laurent Rineau 1e1cb3747a Silent warnings -Wunused-result of g++-4.7

  | Subject: silence warnings caused by -Wunused-result
  | 
  | Hi Laurent,
  | 
  | your changes in 61145 and 61146 to silence the warnings in the Geomview
  | package don't work with gcc 4.7.0 and -Wunused-result. I still see
  | 
  | src/CGAL/Geomview_stream.cpp:148:35: warning: ignoring return value of
  | 'ssize_t read(int, void*, size_t)', declared with attribute
  | warn_unused_result [-Wunused-result]
  | 
  | Maybe one really needs to use
  | 
  | int result = read(...)
  | (void) result;
  | 
  | to silence the warnings.
  | 
  | Joachim

I have not been able to reproduce that with my compiler "g++-trunk (GCC)
4.8.0 20120611 (experimental)".
