-- This tests an oddball case in occam-to-C translation: an array subscript is
-- not constant in C99 (even if it's a constant subscript of a constant).
-- We therefore have to avoid doing the "obvious" C translation of the code below
-- by constant-folding the subscript out of existance -- and making sure it
-- doesn't get pulled back out to a variable again!
