Please see the attachment for details of the result of acct after applying
your patch.

My machine is:
  2 SMP of Itanium 2 (1.2GHz)
  Memory: 8 Gbytes
  Kernel: 2.6.6

BTW. how is your development for "version2" that you posted in this Mar.19.
I have been interested in your V2 format. The account data is very 
useful for performance analysis of processes. It would be more convenient 
if acct datainclude pid and ppid.
Naturally I understood V2 would have some incompatibility against current
acct structure. However I'm sure the value of acct data would become larger
in V2.
I hope V2 structure would be included in 2.7 successfully.
I also found tgid is useful in multithread environment, especially NPTL, to
identify the thread and process of a work-unit. Could you add a tgid field
in your V2 structure?
