Oops, Eli got me (RJ)...

And John got us.
Maybe one should extend it to
+TEMP=%DJDIR%/tmp
+TMP=%TEMP%
+TMPDIR=%TMP%

But this still doesn't solve the problem of maximizing the likelihood
of setting TMPDIR to a drive with enough space, for programs (like
tar) needing it.
using
[tar]
TMPDIR=%DJDIR%/tmp
has (major) drawbacks for people running DJGPP from CD or a network,
but has advantages for people who point their TMPDIR to a ramdrive.

Maybe using something like:
[tar]
+TARTMP=%DJDIR%/tmp
TMPDIR=%TARTMP%
and a note in the README to set TARTMP to a local drive (NOT a
ramdrive) if you are using a networked/CDROMed DJGPP (Yes, this is
ugly, sorry.)
