When I still offered a public access Lynx (I shut it down permanently well
over a year ago.), I built a Lynx specifically for that purpose.  I would
definitely advise against anyone sharing a binary for known users and
anonymous users.

I can see no other way for anyone concerned about the security of their
system.  In addition, I would recommend very rigorous exercising of any
new build before it is offered to the public for execution.

Is the list in userdefs.h all that long now?  When I was doing it, it
was pretty simple to throw an anonymous access specific patch on it.
If `` #define CAN_ANONYMOUS_GOTO_FILE         FALSE '' is set in
userdefs.h, then the anonymous user cannot access file:// urls baring
a bug in lynx.

Glad to hear it!  If anyone on this list is running a public access binary
with no anonymous user defined and only relying on the anonymous switch, don't.
