gnutls 3 round 2

[Riccardo Mottola]

Hi Dagobert (and hi to everybody else too),

since gnutls is important, let's bite the 3.x series.

I noticed you just commited some small tweaks. I have imported your 
BUILD64 suggestion into this branch.

Current status for me is on solaris 9:
serv.c: In function 'listen_socket':
serv.c:774:40: error: 'IPV6_V6ONLY' undeclared (first use in this 
function)
serv.c:774:40: note: each undeclared identifier is reported only once 
for each function it appears in

while solaris10 bails out just little later with:

the receipe is for 3.1.24

The gnutls website states;
current stable: 3.3.18
next stable (what does this mean, unstable?) 3.4.5

should we try out directly 3.3 or any reason to remain on 3.1 ? did 
things get even worse solaris-wise for newer releases?
