Solaris /bin/sh sucks ass, but it has supported functions since at least
2.5.1. That's the earliest Solaris release I have access to, and it's
nearly ten years old?

But it's true, anything in /bin or /usr/bin is of real vintage on Solaris.
/usr/bin/awk isn't even nawk compatible, which is why I always put
/usr/xpg4/bin first in my PATH on Solaris.
