 condition of a FOR statement...

2000-12-28  Geoffrey Keating  <geoffk@redhat.com>

	* c-parse.in (select_or_iter_stmt): Use truthvalue_conversion
	on the condition of a FOR statement, so that it gets typechecked
	and optimised.

2000-12-28  Geoffrey Keating  <geoffk@redhat.com>

	* gcc.dg/noncompile/20001228-1.c: New test.
