Not exactly sure where it came from (looks like an older
version of some cygwin package) but my /etc/profile sets MANPATH
and there are comments in /etc/skel/.bash_profile (and
/etc/defaults/etc/skel/.bash_profile). I see a ".orig" (my vim-
set extension for files I edit - I added some unrelated debug
stuff that came from my linux system).
The comments in the skel files, FYI, say:
# Set MANPATH so it includes users' private man if it exists
# if [ -d "${HOME}/man" ]; then
# MANPATH="${HOME}/man:${MANPATH}"
# fi
In /etc/profile I see [condensed from original version]:
# base-files version 3.9-3
# WARNING -- IF THIS FILE IS MODIFIED IT WILL NOT BE UPDATED
# BY THE CYGWIN SETUP PROGRAM. IT BECOMES YOUR RESPONSIBILITY.
# The latest version as installed by the Cygwin Setup program can

PATH=/usr/local/bin:/usr/bin:/bin:$PATH; export PATH
MANPATH=/usr/local/man:/usr/share/man:/usr/man:$MANPATH; export MANPATH

As cygwin doesn't use "rpm" or any of the other utils that share that
format, it doesn't create any ".rpm{new,orig,save}" files that
contain contain new & old versions of config files & give some indication to
the user that a newer install had changes to the config.
The only thing that is apparent is that some version of /etc/profile
*used* to set MANPATH, but no longer, whereas on my linux box, some distros
have had something like:
MANPATH="${MANPATH:+$MANPATH:}\
`test -x /usr/bin/manpath && /usr/bin/manpath -q`"
has been added for POSIX compatible shells so that "man" can be configured
to pickup system-specific manpath values from /etc/manpath.config.
BTW, as for POSIX compatibility, before 2002, POSIX's charter
said that its recommendations were "descriptive". Its purpose
was to allow future programs to be compatible with what was
already there.
After 2001, or so, the POSIX name changed hands and the new charter
became "prescriptive" (i.e. it started issuing change requirements
that required existing SW to change if they wanted to remain
POSIX compat. These days, you need to specify what version of
POSIX (the Portable, _One_ System Interface data eXchange standard)
you are referring to, since the newer the POSIX version, the more
likely it isn't compatible with what you already have or are used
to.
I.e. it had been intended to apply to new SW being written so
that it would be compatible with what was "out there", but under
new leadership/ownership, was re-chartered to require existing
SW to make changes that were not backward compatible (thus
breaking the original POSIX's portability guarantees). So
sometime after 2000-2001, the new POSIX standard was no
longer portable to existing systems following the original
standard. :-(

Thx alot!
I know that my path is messy, but having "/" in the path should not be
all too fatal.
Furthermore, I probably did not set any of those strange paths myself
(this is afterall Windows ;) ).
@Eliot: Good idea to set MANPATH!
>MANPATH=/usr/share/man PATH="/usr/bin:/foo" strace man bar |grep
'foo/share'
returns nothing and fixes the issue!
IMHO at least in Windows/Cygwin creating MANPATH from PATH makes no
sense! (although I now get the idea what was the rationell!) Reasonably
setting MANPATH should IMHO be a default...
