It also does in the latest version of the proposed "Fix some temp file 
issues" patch <https://lists.gnu.org/r/bug-make/2022-10/msg00064.html>, 
except that if tmpfile fails the diagnostic simply mentions tmpfile. I 
could change that to mention DEFAULT_TMPDIR instead, if you prefer.

In the proposed patch tmpfile is used only on platforms that lack 
fdopen, or that lack dup, so the point I'm raising here matters only on 
unusual platforms (AmigaOS and VMS perhaps?).
