Can do. In fact that was the first thing I did. I do agree in general
casts are the worst way. Then having changed the loop variable type
here, I looked at the other instances nearby where I use a revision
number to subscript this array:

rangelist_array_union(rl_array_t *ma, ...)
   int r;

   for (r = 0; r <= RANGELIST_TESTS_MAX_REV; r++) {
     ma->root[r] = ...

rangelist_array_equal(const rl_array_t *ba, ...)
   int r;

   for (r = 0; r <= RANGELIST_TESTS_MAX_REV; r++) {
     if (ba->root[r] ...

and thought then it looked marginally better to keep using 'int' in
those places (because they're low level operations on the array and
don't care whether the index represents a revision number), and better
to keep consistent than to just change the loop variable in one of the
three functions. But it makes at least as much sense to me the way you
suggest, so I'm happy to change it.
