	/tmp is used by the compiler to store temporary files.  When
	compiling a very large file (or many small files) you run out
	of space on / because of the amount of space used in /tmp for
	C compilations.  You should probably increase the size of
	/ (or move /tmp to another file system, or its own file system).
	Unfortunately, this is usually a painful process on a 3B.  You
	have to boot from floppy, it trashes the disks and you have to
	recover from floppy or cartridge backups, etc.  Fixing a similar
	problem on my old 3B2/400 (increasing swap space in order to run
	INGRES) took about 4 hours of real time.
