To make a more useful suggestion:

#ifndef HAVE___PROGNAME
char *__progname;
#endif

then in main()
#ifndef HAVE___PROGNAME
	__progname = xstrdup(basename(argv[0]);
#endif

It's not a const, though.  Tread carefully.  Make sure not to pass
it to printf()-like functions as a format string, especially in
ssh, where it could be setuid.  etc.

Dave, who can write up a pretty patch if desired, I don't have the portable
      source tree around right now.
