`comp-eln-load-path'.
When removing a package remove the corresponding elns too.
On Windows both of these are performed only when possible, when it's
not the file is renamed as .eln.old and a last attempt to remove this
is performed closing the Emacs session. When a file being deleted was
loaded by multiple Emacs sessions the last one being closed should
delete it.

compilation as a circular load can be triggered if the dependency is
not native compiled already.

* src/comp.c (comp_deferred_compilation): Doc update and set it to
true by default.
* lisp/emacs-lisp/comp.el (comp-deferred-compilation): Remove

system one).

to ignore the compiler context and return the first name.
* lisp/emacs-lisp/disass.el (disassemble-internal): Update the
`comp-c-func-name' call.
Lambda-lists must stay in the same relocation class of the object
referenced by code to respect uninterned symbols.
* lisp/emacs-lisp/comp.el (comp-prepare-args-for-top-level): Break
the original function in a generic specializing for
dynamic/lexical functions. When allocating the lambda-list for
