To my knowledge, there's only 1 Bourne shell, and since it came from AT&T, I 
would expect that to be SYSV (same with ksh, since Steven Korn was also of
AT&T).  I've never heard of a BSD variant of the Bourne shell, nor a BSD 
variant of the Korn shell.  Csh is just the result of a good hacker smoking 
too much crack (keep in mind Bill Joy:

        A) went to Berkeley (need I say more :)
        B) is the same guy who came up with vi!)

I have heard of the "Posix" shell which is often times /bin/sh, but anything 
written for the one, true Bourne shell will work under the Posix sh (but not 
vice-versa).

Of course, this just goes to prove my point:

        When in doubt, write it in perl!

it's the same everywhere :)
