Subject:	"man" completion in zsh not working

This has been a problem for a quite a while to me: the man command
doesn't complete to the possible manpages anymore. For example "man
zsha[tab]" should complete to "man zshall". It worked some time ago in
Cygwin zsh and it stills works on my Gentoo Linux box.

Here are the facts: zsh and man are uptodate. I use exactly the same
.zshrc on both hosts and it doesn't contain any MAN* environment
settings. /etc/man.conf is exactly the same on both hosts ("generated
automatically from man.conf.in by the configure script")

,--- * MANPATH statements in /etc/man.conf
| MANPATH /usr/share/man
| MANPATH /usr/X11R6/man
| MANPATH /usr/local/man
| MANPATH /usr/man
`---

,--- * Cygwin host (where it "doesn't work")
| % echo $MANPATH
| :/usr/X11R6/man:/usr/ssl/man
| ^ see the empty path? ($manpath is "'' /usr/X11R6/man /usr/ssl/man")
| % manpath
| /usr/share/man:/usr/X11R6/man:/usr/ssl/man:/usr/man:/usr/local/man
`---

,--- * Linux host (where it "works")
| % echo $MANPATH
| /usr/share/man:/usr/local/share/man:/usr/share/gcc-data/i686-pc-linux-gnu/3.3/man:/usr/
| X11R6/man::/opt/sun-jdk-1.4.2.03/man:/usr/qt/3/doc/man:/opt/vmware/man
| % manpath
| zsh: command not found: manpath
`---

/etc/zprofile and /etc/profile.d/zshell.zsh don't contain man
settings. When I manually do "export MANPATH=/usr/share/man" then zsh
does the man completion.

My questions are (I know they might not be specifically Cygwin
related):

1. Where and how is $MANPATH assembled?

2. Where does the path that the "manpath" command shows come from?

3. Why does $MANPATH and "manpath" output differ?

4. Why is /usr/share/man not in $MANPATH?

5. Why is the first entry in $MANPATH empty?

6. How and where can I fix this?


Thanks to all that can help,
Thorsten
