I agree with the last statement, but in this case, leaving the const
off the declaration results in a compiler warning about discarding the
inherent const qualifier from a literal string.

A *very* quick look in src/*.c doesn't reveal any other examples of
all-literal argv[] lists like this.  I'm inclined to leave the const
and the cast, but if you have a better suggestion, I'll be glad to
make the change.
