Summarized bug reporting instructions
-------------------------------------

What we need

Please include in your bug report all of the following items, the
first three of which can be obtained from the output of gcc -v:

    * the exact version of GCC;
    * the system type;
    * the options given when GCC was configured/built;
    * the complete command line that triggers the bug;
    * the compiler output (error messages, warnings, etc.); and
    * the preprocessed file (*.i*) that triggers the bug, generated by
      adding -save-temps to the complete compilation command, or, in
      the case of a bug report for the GNAT front end, a complete set
      of source files (see below).
