Well since 95% of the time the issue is pointer size, and since on all
listed architectures sizeof(char *)==sizeof(long int), and since this
is on all listed architectures either 4 or 8, the terrible
combinatorial explosion you bring up seems to be pretty much dealt
with by adding *2* options.

Works for some programs, but hard with others. Seems silly to wear
hair shirts instead of cotton in order to remind ourselves that we
need to knit some silk ones...
