But we already have a test to decide whether we trust, or don't trust,
expr.  I think we should test this too.

# _AS_EXPR_PREPARE
# ----------------
# Some expr work properly (i.e. compute and issue the right result),
# but exit with failure.  When a fall back to expr (as in AS_DIRNAME)
# is provided, you get twice the result.  Prevent this.
m4_defun([_AS_EXPR_PREPARE],
[if expr a : '\(a\)' >/dev/null 2>&1; then
  as_expr=expr
else
  as_expr=false
fi
])# _AS_EXPR_PREPARE
