avahi port and FreeBSD 4.x

[Luigi Rizzo]

hoping someone is interested...
the port is marked "non working" on FreeBSD < 5,
however it at least builds by adding
#include <sys/types.h> to avahi-core/dns.c,
and making sure -lgnugetopt is passed to the linker.

For the former, the patch is simple (below).
For the latter, i just added a line to "configure"

	+LIBS="-lgnugetopt  $LIBS"

but almost surely there is a better way...

cheers
