Problem building gdb with up-to-date sources

[Richard Kuhns]

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!
