Thanks.  The current Emacs sources already have a similar change, but
it also makes sure at startup that a usable temporary directory
exists.  With your change, if none of the environment variables is
defined, the code will crash.

Also, I don't really recommend using a RAM disk for these purposes,
since call-process could result in really large files.
