(C++) patch to parm list handling

[Jason Merrill]

comp_target_parms passes in a TREE_LIST to dump_type, so we need to handle
it, or we get a sorry.  And we don't want to complain if we get a bad
conversion because of our silent rewriting of correct code...

Checked into main branch.

1999-06-25  Jason Merrill  <jason@yorick.cygnus.com>

	* error.c (dump_type_real): Handle TREE_LIST again.

	* typeck.c (comp_target_parms): Don't complain about 
	converting from () to (...) if !flag_strict_prototype.
