Unsetting them in the skel .bashrc files shouldn't be a problem to do, but
on my system...

$ echo $TMP
/cygdrive/c/DOCUME~1/morrijr/LOCALS~1/Temp

Tue Dec 01 10:40 AM
$ unset TMP

Tue Dec 01 10:40 AM
$ echo $TMP


Tue Dec 01 10:40 AM
$

They don't get 'reset' to the windows default... but then, I've not really
been following this thread.  Is that what's wanted?

Also, $PATCH and $TMPDIR weren't defined on my system anyway...
