Earlier I wrote:

	Calling "gcc -Wid-clash-LEN <file name>" sends cc1 into infinite loop
	in which it prints 

		cc1: error: Invalid option `-Wid-clash-LEN'

	on each iteration. The bad code is in toplev.c (line 2848):

			  while (*endp)
			    {
....


The fix in that message was not good enough -- cc1 still issued id
clash warnings for length 0. A better fix is:


		  warn_id_clash = 1;
		  while (*endp)
		    {
		      if (*endp >= '0' && *endp <= '9')
			endp++;
		      else
		      {
			  error ("Invalid option `%s'", argv[i]);
			  warn_id_clash = 0;
			  break;
		      }
		    }
		  id_clash_len = atoi (str + 10);


Sorry for bad fix.
