Description

The current version of Dante (http://www.inet.no/dante/) fails to build with the following error:

Undefined            first referenced
 symbol                  in file
resident                            sockd_child.o
ld: fatal: symbol referencing errors. No output written to sockd
collect2: error: ld returned 1 exit status

The reason seems to be that extern int resident; is declared in tcpd.h but the mapfile is missing it in the global section.

Testing Done

Booted into a system with this change and confirmed that building dante now works.

Ship it!

I think that this looks good. It may be worth checking with Rich to see if we should include size information on this since it's a global variable as opposed to a function.
