Hi All,

 The following was 'recently' committed....

2002-12-17  Jason Merrill  <jason@redhat.com>

   * decl.c (finish_function): Also complain about no return in
   templates.
   * semantics.c (finish_return_stmt): Also call check_return_expr in
   templates.
   * typeck.c (check_return_expr): In a template, just remember that we
   saw a return.

Which in itself is probably a good change, but I've just noticed (from
the Apache Xalan library), that it causes a warning in the following
case...

I meant to comment on this patch when I saw it go by -- I think it's a
mistake.  I think it makes little sense to warn about much of anything
in templates due to problems like these; at the very least, we should
only be warning when the return type is non-dependent.
