Hi,

Attached is a minimal diff to make the vnc port successfully build + run
(Xvnc starts!) on FreeBSD/Sparc64. It doesn't work well yet, however I
thought I'd share my results so far in case someone wanted to help out.
When trying to connect to Xvnc running in 5.1-RELEASE on my Blade 100
from 4.7-STABLE on i386, vncviewer dumps core. Truss log of vncviewer
running on my i386 system when this happens:

^C

IMO, running VNC off headless UltraSPARC systems is a practical way to
run and test GUI stuff without connecing a monitor and keyboard.

Oh, BTW, NetBSD has some useful patches in their pkgsrc patches for vnc,
see http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/net/vnc/.

Cheers,
