Nope. they've been around for a long time.

They can. The Mac was the first major machine that required.

How about:
main(argc,argv)
int argc;
char **argv;
This is a pointer to an array of pointers to arrays of char. To do a
setenv, you basically re-arrange the array or pointers to the new
strings, but the handle (the char**) doesn't change.
