variants

The bug is still present in Apache 1.3.1, and nothing has changed about it in
1.3.2. So it's there also.
>How-to-repeat:
Uncoment "#define TCN_02" at the beggining of the file mod_negotiation.c and
recompile server.
Put files "xxx.html.en" and "xxx.html.fr" into a directory and send the
following headers to the server:
GET /..../xxx.html HTTP/1.0
Negotiate: 1.0
Accept-Language: it
The server will crash.
>Fix:
The following patch for Apache 1.3.1 solves the problem:
--- mod_negotiation.c.orig Sat Oct 3 22:05:04 1998
+++ mod_negotiation.c Sat Oct 3 22:06:27 1998
