;;; The flags naming the features, in every spelling sexc takes. This
;;; is not pedantry about the command line: sextest reads the program
;;; itself and prints the surviving forms to sexc, so a spelling it
;;; does not recognise leaves the guards below resolved against the
;;; wrong set -- quietly, since the test then checks the output of a
;;; program it did not mean to compile.
;;;
;;; --no-platform-features is what makes `#-unix' true wherever this is
;;; compiled, and it has to be honoured on both sides for that to hold.
