Wow, you put /usr/ucb before /usr/bin in your PATH? Brave man.
That test fails because /usr/ucb/basename doesn't conform to POSIX on
Solaris 8 (or Solaris 9 beta for that matter). I installed the
following patch.
2002-03-27 Paul Eggert <address@hidden>
* lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
(AS_SHELL_SANITIZE): Invoke it.
(AS_BASENAME): AS_REQUIRE it, and use $as_basename.
