| If you allow <span class="sc">gdb</span> to set range checking automatically, it |
| defaults to <code>off</code> whenever the working language changes to |
| C or C<tt>++</tt>. This happens regardless of whether you or <span class="sc">gdb</span> |
| selects the working language. |
| |
| <p>If you allow <span class="sc">gdb</span> to set the language automatically, it |
| recognizes source files whose names end with <samp><span class="file">.c</span></samp>, <samp><span class="file">.C</span></samp>, or |
| <samp><span class="file">.cc</span></samp>, etc, and when <span class="sc">gdb</span> enters code compiled from one of |
| these files, it sets the working language to C or C<tt>++</tt>. |
| See <a href="Automatically.html#Automatically">Having <span class="sc">gdb</span> Infer the Source Language</a>, |
| for further details. |
