I dunno, adding those casts doesn't
seem like much of an improvement.  What if some other
compiler starts complaining about them?

How about this idea instead?  Don't insert any casts,
and don't add any "const" keywords.  Instead, replace
stuff like this:

   char *argv[3] = { "program", "-ab", NULL };

with stuff like this:

   static char program[] = "program";
   static char x_ab[] = "-ab";
   char *argv[3] = { program, x_ab, NULL };

This will pacify the compiler.  It's a bit awkward,
but it's bound to be more portable than the casts are.
