	Fix date of previous ChangeLog entry.

Replace some heap vectors with stack vectors.

From http://gcc.gnu.org/ml/gcc-patches/2013-10/msg02735.html

This patch is pretty dull, it just replaces a bunch of things of the
form
vec<T> x;
x.create (N); // N is a constant
blah blah
x.release ();
by
stack_vec<T, N> x;
blah blah
