The bug that the source file isn't known for certain macros such as SETF
and DEFSTRUCT is fixed in the next system.  I fixed this the last time you
reported it, you probably don't need to keep reporting it.  Presumably a
new system will be generated soon.

It is a feature that DEFSTRUCT doesn't automatically space over the named-structure
slot, contrary to what the manual implies but does not say (the writeup in
the manual on named structures is extremely poor.)  Unfortunately no one wrote
down the reason for this decision, but it has something to do with the
case of array-leader structures.  This whole business needs to be revised.

In any case it can't be changed casually, since many people have files which
depend on the present behavior of DEFSTRUCT.
