freebsd stable - Feb 2011 - Problem building gdb with up-to-date sources

Hello,

I just tried to run a buildworld for RELENG_8/amd64 after a fresh csup, and
I'm
getting the following error:

/usr/src/gnu/usr.bin/gdb/libgdb/fbsd-threads.c: In function
'fbsd_thread_get_name':
/usr/src/gnu/usr.bin/gdb/libgdb/fbsd-threads.c:442: error: 'struct 
ptrace_lwpinfo' has no member named 'pl_tdname'

I looked in /usr/src/sys/sys/ptrace.h, and 'pl_tdname' isn't there.
Running 'cvs
log' on ptrace.h, though, shows:

revision 1.34
date: 2010/11/22 14:42:13;  author: attilio;  state: Exp;  lines: +2 -0
SVN rev 215679 on 2010-11-22 14:42:13Z by attilio

Add the ability for GDB to printout the thread name along with other
thread specific informations.

In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
...

Any suggestions? I didn't see anything in /usr/src/UPDATING.

Thanks in advance!

Sorry to followup on my own post, but I figured out what was going on. It 
appears to be a problem with csup.

I've been using csup to maintain 2 CVS Repositories, one at home and one at
work.

The last couple of times I've run csup there were lots of 'checksum
mismatches',
so csup said it would download the entire file. I was watching it this morning 
and saw it going through {/usr/src}/sys, usr.bin, and usr.sbin. It didn't, 
however, actually download all of the files. When it said it was finished 
(successfully!), the last file downloaded was in sys/netinet. This was on my 
home system (amd64).

I tried on a machine a machine at work (i386) with the same results, except that
csup stopped downloading files much earlier. I restarted the csup; it picked up 
where it left off (somewhere in sys/dev) complaining about checksum mismatches. 
It then downloaded a fair number of files but still stopped before reaching 
usr.bin. (Sorry I don't have hard numbers on how many files).

I installed cvsup. It picked up where csup had left off (also complaining about 
checksums), but it updated everything and I've been able to buildworld and 
buildkernel without any problems.

So my earlier problem was due to /usr/src/gnu being updated while 
/usr/src/sys/sys wasn't :-( .
