# This loop iterates through all the permutations of configure OPTIONS.
# This is much easier to maintain, in the event that a new option gets
# introduced, than a bunch of scripts.  If you want to add, for example,
# switch, direct, and inlined-threading modes, multiply the current loop
# count by 3 (8 * 3 == 24), and then introduce tests for whether (i % 3)
# equals 0, 1, or 2, and then divide by 3.
