Thanks to Tom Blinn and Charles Richmond, and some experimentation, I found
that indeed, getopts is not well supported in sh under DU.
Tom pointed out that under DU 4.0 and later, sh has two versions. One (the
better one) is POSIX/XPG4 compatible and supports what I want. The older
one does not.
ksh supports everything I need. Now to see how to rectify the problem.
Under DU, ksh seems to be /usr/bin/posix/sh, which is the POSIX/XPG4 sh.
