New Revision: 154844<br>

Log:<br>
Implement the last part of C++ [class.mem]p2, delaying the parsing of<br>
exception specifications on member functions until after the closing<br>
'}' for the containing class. This allows, for example, a member<br>
function to throw an instance of its own class. Fixes PR12564 and a<br>
fairly embarassing oversight in our C++98/03 support.<br></blockquote><div><br></div><div>This feature was removed from the language in DR1308 (which was voted into the WP at Kona).</div></div>
</blockquote></div><br></div></div><div>Richard and I have discussed this, and we think that removing this feature from the language is in error. We'll continue to implement the pre-DR1308 wording and bring the issue up for discussion again at the new committee meeting.</div>
