[Axiom-developer] depsys

[Gabriel Dos Reis]

Tim --

I have a question about a difference in "load" behaviour bewteen a
clean lisp image (GCL), and depsys (and any image derived from it).

In a clean image, when I say '(load "foo")', Lisp will try to search
from the current directory -- just what is expected.

However, depsys will start search from $AXIOM/.. -- which is less expected.
I spent quite lot of time figuring out where that behaviour is
implemented in the files that make up depsys, but I was unsuccessful.
Do you have an idea whether that behaviour is implemented?
I looked many times at reroot, but could not deduce how it might be
responsible.  It looks like there is an Axiom code that fundamentally
changes GCL's usual load procedure.

Here is an excerpt of a ssession that reproduces the problem.
