I guess you're right that W::W(int) should be defined.
And the question is why it isn't diagnosed during instantiation, sure.
The initialized (omp_priv (12))
etc. clause means that for the type(s) for which the declare reduction
is defined, when omp-low.c privatizes the variable, it should be done
as if the source contained W var (12);
This is done by attaching code to call the right ctors/dtors to the clauses
and omp-low.c emitting those sequences.
