just as an add-on hint, a sample implementation of pushd/popd/dirs
(not just for ksh, works with sh too) is contained in the sh-source
in the NetBSD source tree, in [/usr/src]/bin/sh/funcs.  You only
have to include one of the files here since they all contain the
same.  It's not written in the best style (I cleaned up my copy a
little bit before using it) but it works quite well and "authentic".
Another implementation can be found in Korn and Bolsky's ksh book
and I guess there're more on the 'Net.  In comparison with bash,
I prefer to extend the shell dynamically via scripts etc. than
having everything imaginable compiled into it.
