The thing is, it is not even necessary to point Autoconf configure
scripts at a reasonable shell. The configure script will find a capable
shell and run itself with that shell.

UnixWare has a /bin/sh as crufty as Solaris 10. I just pulled the
latest config.guess and config.sub into my OpenSSH tree and configure
was just as happy as before. Like Solaris /bin/sh, UniWare's does
not handle $(...) either.
