The only man I can find which does support -w or --path is the GNU one.
The exit code of != 0 seems fine on the systems I've looked at provided
stderr is redirected.

What are you trying to achieve with man -w - find a default manpath to
use if $manpath is unset? As far as I can tell man -w only gives you the
location of a specific man page which isn't entirely useful for finding
a default manpath as the default can (and often will) contain more than
one directory. The only way I know of finding the default manpath is by
running the man binary through strings. Maybe we could use a for loop to
guess possible man directories and check them.
