Re: On the behavior of `c-beginning-of-defun'

I did not test all cases but only the case that function
`c-beginning-of-defun' fails.  I think it is almost Ok.  However,
please try the following case, it might be a bug.

Suppose `-!-' indicates the position of point.  If point is, for
example, in the body of function `main1':

   /* 1. K&R C.  */

   /* This will not get correct result until the bug in CC mode is fixed.
      See
      http://lists.gnu.org/archive/html/emacs-devel/2006-12/msg01341.html  
*/
   int
   main1 (argc, argv)
        int argc;
        char *argv[];
   {
     -!-/* ...  */
   }

Then `c-beginning-of-defun' moves point to before ``int'':

   /* 1. K&R C.  */

   /* This will not get correct result until the bug in CC mode is fixed.
      See
      http://lists.gnu.org/archive/html/emacs-devel/2006-12/msg01341.html  
*/
   -!-int
   main1 (argc, argv)
        int argc;
        char *argv[];
   {
     /* ...  */
   }

Which is a desired behavior.  But if point is just after ``[]'':

   /* 1. K&R C.  */

   /* This will not get correct result until the bug in CC mode is fixed.
      See
      http://lists.gnu.org/archive/html/emacs-devel/2006-12/msg01341.html  
*/
   int
   main1 (argc, argv)
        int argc;
        char *argv[]-!-;
   {
     /* ...  */
   }

`c-beginning-of-defun' moves point to the start of the file, rather
than the desired position.

This is the only problem I can see until now.  Thank you very much.
