statedir, lockdir?

[Shaddy Baddah]

Hi,

My question is pretty much as per the unanswered question from 
http://calypso.tux.org/pipermail/xemacs-beta/2007-June/011421.html.

I cannot find where the --statedir configure option is used, and 
strongly suspect that it is unused at all.

Can anyone confirm this? In fact... I had real trouble finding its use 
all the way back to pre 21.4.

Regards,
Shaddy
