I still think, like Jason, that all the environment variables frobbing
on w32 should be in w32.c:init_environment, not in Lisp.  Moving it to
Lisp means, e.g., that temacs will have different ideas about HOME
etc. than the dumped Emacs, which I think might confuse someone some
day.  See below for another reason.

This change means that we run this code every time getpwuid is called.
That's too excessive, I think, and could be avoided if all the
environment frobbing were done in C.
