Yep, for me, too:
CYGWIN_NT-4.0 1.3.2(0.39/3/2) 2001-05-20 23:28 i686 unknown

But i use this script (bman) which makes an output to InternetExplorer,
i get the stackdump, but i also get the output to the browser.
Default usage see above commands.

BMAN:
=====
#!/bin/bash

if [[ -z $MANPATH ]]; then
    manpath="/usr/local/man /usr/man"
else
    manpath=${MANPATH//:/ }
fi

startcmd="`cygpath -u -S`/cmd /c start"

if [[ $# -gt 2 || $# -eq 0 ]]; then
    echo
    echo Usage: `basename $0` [section] topic
    echo
    exit 2
elif [[ $# -eq 2 ]]; then
    section=$1
    topic=$2
elif [[ $# -eq 1 ]]; then
    section='?'
    topic=$1
fi

tmpfile=/usr/doc/Manpages/$topic.html
rm -f $tmpfile

manfile=
for m in $manpath; do
    for d in $m/man$section; do
        if [[ -d $d ]]; then
            for f in [[ $d/$topic.* ]]; do
                if [[ -f $f ]]; then
                    manfile=$f
                    break 3
                fi
            done
        fi
    done
done

if [[ -z $manfile ]]; then
    echo
    echo `basename $0`: no man page found for $topic
    echo
    exit 1
else
    if [[ $manfile == *gz ]]; then
        zcat $manfile | man2html > $tmpfile
    elif [[ $manfile == *bz2 ]]; then
        bzcat $manfile | man2html > $tmpfile
    else
        man2html $manfile > $tmpfile
    fi
    chmod +x $tmpfile
    $startcmd `cygpath -w $tmpfile`
fi
#====
#END:

With this script you will have the HTML-Output in /usr/doc/Manpages 
which needs to be created if it does not exist. You may also change
the drive in the script pointing to another location.
