FWIW
on my cygwin, 2.11.0(0.329/5/3), I have who (GNU coreutils) 8.26.
Of all the options -a/--all gives:
$ who --all
roger    - pty1         2018-10-16 13:05   .           276 (10.40.90.15)
-u, -H, -m, -s, -u gives the same (plus/minus a '-' or '.')
-q seems reasonable, at least similar to the same command on fedora
--version, --help give expected output.
The rest return nothing, including -b
