I don't mean to beat this dead horse into the ground, but there
would only be a problem there if you had:
const char *strrchr( const char *string, int c );
But you don't; the return value is *not* const, and that's what
you are using in your assignment. Granted, the return is an
alias for a string declared as const, but to me this is simple
pilot error, nothing wrong with the aircraft... ;-)
