Unfortunatly this is not true.  I noticed in passing that I had whoami
in /usr/local/bin on my system, and for unknown reason I assumed that
it was part of the GNU bin tools distribution.  In fact my copy is
from the BSD free sources, and was distributed as part of the MGR
distribution for xenix.  Since the source is so small I've include
the shar file below.

Enjoy
