I have been wondering if "x" could be an expression that has an operator
that binds weaker than the assignment '='.  That may necessitate the LHS
of the assignment to be somehow marked as bound the tightest, i.e.

#define REALLOC_ARRAY(x, alloc) (x) = xrealloc((x), (alloc) * sizeof(*(x)))

Or am I being overly silly?
