I think you nailed it!

Note that I dont rely on "any weird" dependency tricks, I do exactly
what Emacs itself does by generating a loaddefs file that contains the
right autoloads, so that that file can be pulled in during compile time
for compiling the .elc file for each module.

The emacspeak-preamble file contains Emacspeak's own core "require "
statements as well as a couple of critical macros.

Eli's suggestion to use the bootstrap related build function is
something I'll try next -- that might well help.

I'll see what emerges in the next couple of weeks, then write things up
as appropriate --- Eli in a nutshell, what I'm trying to do is
effectively now spread over a few threads from me -- TL;DR: "I'm trying
to compile and use Emacspeak " which works, But at present it produces
warnings that looks spurious and there may well be corner cases that are
broken, though I've not found any.

The Emacspeak  codebase is  strict with respect to byte-compiler
warnings, I dont have *any*  in the core --- and package-specification
extensions compile with no warnings as long as the dependent package is
installed.
