[FreeRADIUS 3.0.16] Threads (Probable) Typo

[Sergio NNX]

Hello.

We have received a report showing the following error message:

Tue May 15 08:25:49 2018 : Error: Failed binding to auth+acct address 192.168.1.36 port 2083 (TLS) bound to server default: Bad file descriptor
Tue May 15 08:25:49 2018 : Error: \freeradius-server-3.0.16\etc\raddb/sites-enabled/tls[7]: Error binding to port for 192.168.1.36 port 2083

The IP address shown above is valid.

Digging a bit in the code base (listen.c) has led us to the following line:

                #ifdef HAVE_PTRHEAD_H

After fixing that, now we see (radiusd -Xxx):

Tue May 15 10:16:50 2018 : Error: \freeradius-server-3.0.16\etc\raddb/sites-enabled/tls[7]: Threading must be enabled for TLS sockets to function properly

Running 'radiusd -fxx -l stdout' shows:

...

We are not familiar with TLS but the message:

        'Threading must be enabled for TLS sockets to function properly'

seems misleading.

Any help would be appreciated.

Thanks in advance.
