Yes.  This would not be for use in GCC itself.  Paul has a good point
that in some contexts the extra initialization is too costly, but the
'a=a' idiom is not documented, nor is it obvious to a reader that its
sole effect is to silence this warning.  So I think we should have a
more readable way to get that effect.
