The casts to int in CLS_SUBTABLES_FOR_EACH_REVERSE are not so great.
One might avoid them with something like this:
#define CLS_SUBTABLES_FOR_EACH_REVERSE(SUBTABLE, INDEX, SUBTABLES) \
for ((INDEX) = (SUBTABLES)->count; \
(INDEX)-- > 0 && ((SUBTABLE) = (SUBTABLES)->array[INDEX], true); \
)
or alternatively one could use a predecrement on the [INDEX] instead
of a postdecrement on the > test.
That covers my comments from the previous revision. I didn't look at
the other code because I assumed that it didn't change much. Let me
know if I should look again.
Thanks,
Ben.
