When 'clisp-link' is used to create a linking set B from a linking set A
and some modules M1, M2, ... [in our case A = base, B = full]: why does
it need to do anything with the types that are already in *c-type-table*
of A ?

Is clisp-link starting out with the 'boot' memory image and adding the
modules from A and the modules M1, M2, ... to it?

Or is clisp-link starting out with the memory image from A and adding the
modules M1, M2, ... to it?

If it's the first case, then why? Why not use the second approach?

If it's the second case, then why the need to rebuild the *c-ctype-table* from
scratch?

(Sorry, I didn't have time to look how the code does it.)
