This can only be done by the users, and then they should set TMPDIR in 
the environment.

DJGPP.ENV cannot handle this, since you have no idea what kind of drive 
is the one where %DJGPP% points.  It can be a CD-ROM, for example.

This can happen (and indeed happened to me), but only on very rare 
occasions.  One example is the shell script used in building TeX, which 
is why the README.djgpp file there says to make sure RAM disk is large 
enough.  Another case is when you build dictionaries for Ispell: the 
monstrous shell script that is run then produces 10MB of temorary files.
