  There were earlier version of UNIX which lackled the call (it's
getcwd, by the way), but it's in recent versions of SysV, Xenix, etc.
And there was never a reason to do more than one, and /bin/pwd is a
program which could be run directly, father than by forking a shell as
noted in the original posting, etc.

  In other words there's no reason for a problem, it's just a bad
implementation one that system. Also, until I looked at the accounting
file, I find it hard to believe that the fork happens more than once on
any system. I don't say it doesn't, just that I want to see it.
