The attached patch makes -finit-<type>=<constant> generate default
initialization for automatic arrays.
It was OK for the trunk - is it also OK for the 4.6 branch ?
Strictly speaking, it doesn't fix a regression, it is a fix for a
(non-default) debugging option.

* resolve.c (build_default_init_expr): Allow non-allocatable,
non-compile-time-constant-shape arrays to have a default
initializer.
* invoke.texi: Delete the restriction on automatic arrays not
being initialized by -finit-<type>=<constant>.
