[patch] unify free- and fixed-form diagnostic messages

[Bernhard Fischer]

Hi,

Attached patch makes two warning messages consistent between fixed-form
and free-form.

Ok for trunk and 4.1?

2006-03-21  Bernhard Fischer  <aldot@gcc.gnu.org>
	* parse.c (next_free): use consistent error string between
	free-form and fixed-form for illegal statement label of zero.
	(next_fixed): use consistent warning string between free-form
	and fixed-form for statement labels for empty statements.
