  SVN rev 183023 on 2008-09-14 16:52:42Z by marcel
  
  Widen psaddr_t from uintptr_t to uint64_t.  This results in an
  ABI change on ILP32 platforms and relating to events.  However
  it's harmless on little-endian ILP32 platforms in the sense
  that it doesn't cause breakages.  Old ILP32 thread libraries
  write a 32-bit th_p and new thread libraries write a 64-bit
  th_p.  But due to the fact that we have an unused 32-bit data
  field right after th_p and that field is always initialized to
  zero, little-endian ILP32 machines effectively have a valid
  64-bit th_p by accident. Likewise for new thread libraries and
  old libthread_db: little endian ILP32 is unaffected.
  
  At this time we don't support big-endian threaded applications
  in GDB, so the breakage for the ILP32 case goes unnoticed.
