We can suggest create another function, which effectively builds up a
temporary name suitable for passing to mkstemp() that takes into
account TMPDIR (with full error checking). Or we add a flag to
mkstemp() to do this, or something.

There should be a standard way for programs to say "let me use $TMPDIR"
if necessary, rather than reinventing the wheel in all these programs.
