I think they would work, and for small data sets, they are fine.
I'm not too happy with the replication they cause in `testsuite' -- one
of my ideas was to test on the order of 2^8 link flag combinations
eventually, and I would like to keep the blow-up as small as possible.
I understand that having both m4 constructs and shell loops work
together is quite difficult.

Thanks for your suggestions, though.
