I guess a side question here is if TMP does not exist then should it
be defaulting to the system wide TEMP variable, the one defined in
.bashrc for the user or should it even be created at all?  I posted an
strace and it shows TEMP set to /tmp but patch still uses TMP instead
and since TMP doesn't exist it looks like cygwin sets TMP to the
system wide one by default.  On linux patch uses whatever TEMP is set
to and doesn't use TMP if it isn't set.  If I set TMP then it uses
that instead so it has an obvious preference to it.

The linux distribution was Debian or a close derivative.  I don't
maintain the server I tested on.

P.S. - On linux (when I tested) TEMP, TMP, and TMPDIR were not set and
patch defaulted to /tmp.
