At least some versions of Windows have it; NT 5.x has a per-user
tempfile directory, as I remember, and perhaps some of them lack the
global c:\temp directory.

Perhaps "get_tempfile_path()" should default to "c:\temp" if it exists,
and "c:\" if it doesn't.

Also, note that there's a routine "create_tempfile()" in "util.c" - but,
on UNIX, it defaults to "/var/tmp" rather than "/tmp".  Should it use
"get_tempfile_path()"?  And should "get_tempfile_path()" default to
"/tmp" or "/var/tmp" on UNIX?  The former is often cleaned on reboot,
which might be a bug or a feature; on SunOS 5.x, it's implemented as an
in-virtual-memory file system, which means it might run faster than
"/var/tmp".  However, "/var/tmp" is often on a file system with more
space than "/tmp", so *large* temporary files should perhaps go in
"/var/tmp".
