Right. The attached script produces this output on my system:

/tmp
/tmp

/tmp
/tmp/tmp

Anyway $TEST_DIR and hence `pwd` (builtin or not) seems to work
properly on all systems, so it looks a safer choice.

No.

On Solaris 10 /bin/sh is a bourne shell (thus it has a builtin pwd
much like the korn shell).
