Great if you really want to clobber other arguments and/or
environment variables.  argv[0] is a pointer to a string that
was set up for you by the exec() system call, or at least by
the C run-time startup module.  There will not in general be
enough room to hold a long string like that, so the strcpy()
would overwrite other useful stuff as well.

Why bother?  Are you trying to run games on a system where
you're not supposed to, or what?
