`who' isn't ported because it doesn't make sense in the DOS/Windows
environment: there's only one user logged in at any given time, and
the only information `who' can print is its username, which is what
`whoami' does.  `whoami' *is* ported and _should_ be built if you
compile Sh-utils.

Right.  `who' depends on facilities which don't exist on DOS/Windows,
and since it wasn't ported for the reasons I described above, no
alternative facilities were invented.

Why would you need `who' on DOS/Windows, anyway?
