I recently installed the w3m package.  When I tried to display the
help page by typing "H", I got only a blank page with this message
in the status line:

    ≪ ↑ ↓ Viewing <w3mhelp.cgi>     No Line

I did some poking around, ran w3m with strace, and found that w3m
runs the script /usr/libexec/w3m/cgi-bin/w3mhelp.cgi to generate its
help page.  When I ran that script alone, I got this message (on one
line):

    Can't use 'defined(%hash)' (Maybe you should just omit the defined()?) at /usr/libexec/w3m/cgi-bin/w3mhelp.cgi line 51.

I did that, as shown in this diff:

    $ diff w3mhelp.cgi.orig w3mhelp.cgi
    51,53c51
    <       if (defined(%funcdesc)) {
    <           $lang = $tlang;
    <       }
    ---
    >       $lang = $tlang;
    >

Having done that, the "H" help function works fine.  So, I have
a workaround for the problem, but I'd really like a proper fix, and
there may be other users with this problem.

I also recently installed w3m onto my Ubuntu 20.04.3 LTS system and
the w3m help page displays fine there with no modification to that
file.

To see the problem:

    1.  At the bash prompt, execute
            $ w3m -v
    2.  Type
            H

The package appears to be installed properly:

    $ cygcheck -c w3m
    Cygwin Package Information
    Package              Version        Status
    w3m                  0.5.3-3        OK

The output of "cygcheck -s -v -r", sanitized, is attached.
