recent changes to libc on amd64

Hi,

On 14.Jan. I have rebuild world and kernel and I can report
that at least two things are broken on amd64. First, Xorg
can't be started (I have tried rebuilding
ports/x11-servers/xorg-server but this is all I get when
I try running X:

# X

X Window System Version 6.8.2
Release Date: 9 February 2005
X Protocol Version 11, Revision 0, Release 6.8.2
Build Operating System: FreeBSD 7.0 amd64 [ELF]
Current Operating System: FreeBSD magarac 7.0-CURRENT FreeBSD 7.0-CURRENT 
#0: Sun Jan 15 10:17:46 CET 2006 
root_at_magarac:/usr/src/sys/amd64/compile/TEST amd6
4
Build Date: 15 January 2006
         Before reporting problems, check http://wiki.X.Org
         to make sure that you have the latest version.
Module Loader present
Markers: (--) probed, (**) from config file, (==) default setting,
         (++) from command line, (!!) notice, (II) informational,
         (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(==) Log file: "/var/log/Xorg.0.log", Time: Sun Jan 15 13:20:37 2006
(==) Using config file: "/etc/X11/xorg.conf"


and nothing happens. I have also noticed that joe is broken too
(it was running fine before):

# joe /etc/X11/xorg.conf
Processing '/usr/local/etc/joe/joerc'...Segmentation fault (core dumped)
#

I don't know if  this is just amd64 related since it will take me some
time to rebuild on i386.
