I don't know if bs is truly an extension of bc, but here is a little
information I got from peeking at the source:
   1) bs is attributed to IBM - that is, it contains only IBM copyrights,
      but that does not necessarily mean that we wrote it all here.  Possibly
      somebody did it for hire.  It was available on earlier versions of
      AIX.  Ah, I find that we got it from ISC originally in 1985.
   2) The version of bc that I find in Version 3 has copyrights from AT&T,
      Cal-Berkeley, and IBM.
   3) The source for bs and the other AIX Version 3 commands and libs has
      been sent to OSF many times over.  Maybe you have access that way.
      I don't know what our position is right now about making source to
      AIX Version 3 available.  Sorry.  I just work here.

Also, bs is written in C, whereas bc is in yacc, if you care about that.
