There is some  luck possible here.  If   the only thing  you're having
problems  with is during  compile sorts of things,  then it is easy to
change   the temporary directory  used  by   many  versions   of "cc".
Obviously,  this won't cure all  your  problems if some other sorts of
stuff are crowding /tmp.

Assuming you have plenty of space in /usr/tmp, try

	TMPDIR=/usr/tmp; export TMPDIR

(some "cc"'s use TEMPDIR instead).

To  see if this  causes "cc"  to use /usr/tmp,  just do  a medium long
compile  and abort  it in  the middle.  The scratch files  are usually
left hanging around, so see if they show  up in /usr/tmp.   If so, put
the above line in /etc/profile and  that should  unclog /tmp  for you.
(Some "cc"'s use /tmp by default, others /usr/tmp.)
