Rodrigo,

Thank you. Your mod to /bin/nroff provided as an attachment at
http://www.cygwin.com/ml/cygwin-xfree/2004-03/msg00299.html worked
perfectly. That is, an xman page now appears with the expected enhanced
view rather than the escape codes.

As a separate issue, I have noticed that any attempt to view a second xman
page is defeated (at least in XP Pro) with an error message as follows:

    Xman Warning:
    Something went wrong trying to run the command:
    cd /usr/man ; tbl /usr/man/man1/{requested page} | neqn | nroff -man
..{rest of msg off screen}

and

    cannot create /tmp/xman002688: permission denied

whose solution may reside in something to do with permissions rather than
Xman ...

 Fergus,

See

http://sources.redhat.com/ml/cywin-xfree/2004-02/msg00158.html

and 

http://sources.redhat.com/ml/cywin-xfree/2004-02/msg00185.html

I undertand that the only way to make xman function properly is to
modify the script /bin/nroff in order to force the -c option. That is not
a clean solution. What should be done is to modify Xman in order to
include the -c option when Xman calls nroff. I believe that that
should be done by the XFree mantainers. In any case in the attachment
there is the modified nroff.

Problem with xman

[fergus]

I'm running XWin -51 and the 20040306 snapshot. If I try "xman" then
everything looks as though it's going to work beautifully (and it does, as
far as file access etc goes) but a typical man page, when it appears, shows
control instructions like this:

1mNAME0m
        diff - compare files line by line

1mSYNOPSIS0m
        1mdiff 22m[4mOPTION24m] ... 4mFILES0m

etc.

Anybody else get this? Do I need to do something simple to correct this
behaviour?
