[Bug c/22308] New: Failure to diagnose violation of constraint 6.516p2

["neil at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

With -ansi -pedantic-errors, GCC fails to reject the following assignment.

struct foo s;
volatile struct foo t;
struct foo { const int z; };

void bar (void)
{
  t = s;
}

GCC is tricked by the delayed completion of a qualified form of the type.
