What does Axiom care about temporary files generated by GCL?
Isn't the goal just to compile and load a Lisp function?

Do you mean to suggest that GCL can not be successfully used on a
multi-user system? Surely this is not a problem with must software
intended to run on unix/linux? There is a standard unix function
to create unique temporary file names in a multi-user environment.

In my experience the gazonk files are always created in /tmp
in all version of Axiom I have used so far - for both explicit
SPAD compiles ")compile xxx.spad" and for implicit function
compiles ")set function compile on". The axiom draw operation
always seems to try to compile it's first argument and for some
reason leaves some gazonk files in the /tmp directory - not only
when it fails but all the time. If the resulting gazonk file is
owned by the current user then everything is ok. But if the file
is owned by another user/group to which I do not have write
access, then the next time someone else tries to use the Axiom
draw function, an error like this:
>> System error: Cannot create the file /tmp/gazonk0.fn.
occurs. Does this error message originate with GCL or with
something else that Axiom is trying to do with/too this file?
