AFAICS in open source Axiom *read-default-float-format* always was
set to single-float. CCL based Axiom set *read-default-float-format*
to double-float. GCL uses the same precision for single and
double floats (and also for long float), so for GCL it does not
matter very much. Do you think we should set *read-default-float-format*
to T? I must admit that in Lisp/boot sources I would prefer to
explicitly specify double precision (when needed), while for
Spad/input we are (or should be) using our own routines anyway.
Concerning *load-verbose*: in my sbcl-based Axiom it is set
to nil (the intended value) -- the same as in GCL or clisp
based version. I am not sure if we care about other special
variables: we I think set them to required value during affected
operations.
BTW: If you want to have quiet compilation/loading it is not
enough to set *load-verbose* and *compile-verbose* to nil.
One also have to handle various conditions (see for example
|load_quietly| in axiom-lisp.lisp.pamphlet).
