The discussion currently going on in the thread

   http://cygwin.com/ml/cygwin/2009-11/threads.html#00892

makes me think that the section on environment variables in the user's 
guide (http://cygwin.com/1.7/cygwin-ug-net/setup-env.html) could use 
some expansion.  For example, it's not stated explicitly which Windows 
environment variables get imported into Cygwin (all of them?), nor is 
there a complete list of variables containing paths that get converted 
to Unix format.  PATH, HOME, and LD_LIBRARY_PATH are mentioned, but 
TMPDIR, TMP, and TEMP are omitted.  I think the last three should be 
listed, along with the suggestion that users might want to unset them in 
the Cygwin environment.

I would be willing to take a stab at writing a patch if the developers 
think this would be useful.

Ken
