* build-aub/general.m4sh (lt_HAVE_PLUSEQ_OP): Instead of using $((..)) arithmetic, which causes an error on dash, use a case based bash version check. (lt_HAVE_ARITH_OP, lt_HAVE_XSI_OPS): Also short circuit the feature probing forks and set these automatically when zsh is detected. Reported by Stefano Lattarini. Signed-off-by: Gary V. Vaughan <gary@gnu.org>
