I have had success with the following base construct, so I volonteer
to go ahead along these lines. AC_PATH_PROG and AC_VAR_ARG are the key
ingredients for searching and overriding. The test run gave me a good
way of testing "func_id_uid" and "func_id_user" which were needed as
work around for a troublesome early Belenix, i.e., OpenSolaris version.
