ask-user-about-super-session-threat function

Greetings,

I am currently using XEmacs 19.14 (Yeah, I know it's old, someday I hope
to move up).  I am using the solaris version on a Sun workstation.  If I
modify a file that is stored on the solaris workstation, I have no
problem.  However, most of my files are on a Windows NT workstation, the
drive is an NTFS, and is configured to be sharable.  I am able to create
and modify files on the NT using the solaris XEmacs.  But about 50% of
the time when I try to modify a file that I have saved during an XEmacs
session, I get the message "filename changed on disk: really edit the
buffer? (y, n or C-h)"

There is no one else modifying any of these files.  It is as if XEmacs
is having a problem with the date and time of the last modification of
the file on the NT machine.  If I say yes to the prompt, I am able to
modify the file, when saving it I get the message "filename has changed
since visited or saved.  Save anyway? (y or n)."  I then answer yes and
the file is saved.  This is more of an irritant than a serious problem.

I saw it on web that it is suggested to define function ask-user-about-super-session-threat
to do nothing. But I don't know where to find the def. of the function and how to change it. May I have more hints? Thank you so much.
