What I'd like to do (without copying or mallocing and without
using a VLA)
is to get a pointer to a slice of argv, specifically,
{"one", "two", "three", "four"}.
In Python terms argv[optind:argc].

Presumably the declaration that was intended is something more
like

  const char *(*argv_slice)[argc - optind] = (void*) &argv[optind];

It should be noted that this solution satisfies the stated
requirement of not using a VLA, but it does rely on using
a variably modified type.
