Subject: VAX C - relative adresses?

A question directed at VAX C gurus:
I would like to create a static table of address offsets in VAX C, like
        static <type> base
        extern <type> item1,item2,...
        static readonly int tab[size] = {&item1 - &base,&item2 - &base, ...}
so I'd have POSITION-INDEPENDENT data only (for use in a shareable image)

Now simple adresses (+- offset) are legal initializers in C,
but not their difference, so the above program won't compile,
while
        static readonly char *tab[size] = {&item1,&item2,...}
is o.k.

Do you know of a way to convince VAX C to do the desired
(compile-time) initialization?
