Deja vu... I quote from <18201:Sep2203:25:3190@kramden.acf.nyu.edu>:

: A different approach should work under any C compiler, though it may not
: be implemented efficiently. It also has the usual syntactic problems of
: macros.
:
:   static struct { struct xtag x; struct ytag y; }
:     shmoe = { &(shmoe.y), &(shmoe.x) } ;
:   #define x (shmoe.x)
:   #define y (shmoe.y)
:
: Caveat: This is untested. But the idea is useful to remember.

I think the conclusion of the discussion was that there's no (other)
portable solution.
