In that case, I think we should leave autoconf alone.  Autoconf will
use dirname in preference to expr, if dirname works.

Your expr is clearly buggy, since it thinks that the pattern /[^a]/
matches the string "a".  Is BeOS still being maintained?  If so,
please send the maintainers a bug report; their regular expression
matcher is broken.
