Thanks Dave.

Hmmm, hpux-thread.c is:

 - implemented on top of deprecated_child_ops.  deprecated_child_ops is
   just a dummy target that does nothing.  This was an alternative to removing
   hpux-thread.c completely at some point in the past.  So this file is just
   dead wait at this point, patiently waiting for someone to salvage it.

 - implemented as a process_stratum target using the ancient
   child_suppress_run hack.  Salvaging this target would mean turning it
   into a thread_stratum target.  I'm looking at the code, and I can
   tell you that without adding any new features, just translating the
   mechanisms, that most of the file would disappear.  The mildly interesting
   bits left are the register access code, and the objfile callback that
   detects the thread support is active in the inferior.  We're talking about
   a couple dozens of lines of code.

 - The bit rot breaking the build is now in the register access code...

So, although the build breakage this time is probably easy to fix, IMO,
we should just move the file into the attic.  It may
be even less work to start from scratch than to resurrect it into functional
state.  The file will always be in the attic for anyone wanting to salvage
this.  (I didn't go look for the current debian patch to see what they did to
this file.)

Comments/Objections?
