    We already run programs from various Emacs features, without fear of a 
    crash.  Also, running programs to probe their functionality is a standard 
    way of testing things in configure scripts.

It is undesirable to do this in configure scripts because that makes
cross-compilation impossible.  Doing it when running Emacs is better
because it does not cause such a problem.
