The problem is that in C89 only the first member of the union is
initialized.

The obvious solution is:
    union U u;
    u.d = 1.2;
But that works only if u has automatic storage duration.

You could also define a function that takes a double argument and
returns a union U result.

Of course the best solution is to use C99 or later, unless there's
some reason you can't.
