Thank you for the report. It looks like you have stumbled on an 
infrequently tested path, and looks like the error recovery mechanism in 
m4 has a bug when encountering low disk space due to a quota.

As for completing your build, you'll have to find a way to enlarge the 
quota.  In the meantime, we'll have to figure out what the actual bug is 
in the m4 error recovery code and repair it before the next m4 version 
is released.
