Default HOME to USERPROFILE on w32?

[Lennart Borgman]

There was a discussion in oct 2004 about what to do on w32 if HOME env 
var was not set. I think the decision pretty much was to use 
USERPROFILE. There was one exception: If c:\.emacs existed then this 
should be used instead. (See for example 
http://lists.gnu.org/archive/html/emacs-devel/2004-10/msg01168.html).

It does not seem like this has been implemented. Are there any 
objections do this?
