It will use the output of the expr and then append the output of the
sed. So we'd get a 0 . or something similar.
I see. How about if we add an AC_PROG_EXPR that searches for a
working expr and sets EXPR to its value, or to "false" if it can't
find one. Then AS_DIRNAME_EXPR can AC_REQUIRE([AC_PROG_EXPR]) and use
"$EXPR" instead of "expr".
