This is an example of an initialised union; explicit initialisation of unions
is not permitted in X3J11. Almost quoting the draft standard ``static objects
not initialised explicitly are initialised as if every *scalar* member
were assigned the integer constant 0 ''.

Now a union is not a scalar object. But its members would seem to be.
Perhaps herein lies an ambiguity.
