Ha ha! Yes, that's how my fingers would more naturally phrase such a
thing. But I *believe* that is a bash-ism. I tried to be as generic as
I possibly could by reviewing the automake/autoconf/m4 script gotchas
someone referred us to a while back (I think it was Alan Coopersmith).
Reviewing the pertinent sections I believe what I wrote is the most
generic, but I could be wrong.
