Problem reported by Patrick Pelissier in

More fallout from the same 2.66 regression that was partially fixed
yesterday, but until yesterday's AS_LITERAL_IF actually treated \ as a
non-literal, apparently no one noticed the latent bug of a spurious
call to AC_CHECK_FUNC([\]) during automake's libobj5.test.
