Not sure what this means. Is this a "make bootstrap", or is it
something close yet different?

Of course, these may be due to simple "infinite recursion" problems
fixed by bootstrapping. But they may also be due to "deep recursion",
in which case increasing max-lisp-eval-depth might help (IIRC I had to
bump this limit when I introduced eager macro-expansion, so it wouldn't
be a big surprise if it needs to be bumped yet a bit higher).
The eager macroexpansion can cause fairly deep recursion, especially
if/when some of the code (e.g. macroexp.el) is not yet byte-compiled.
It shouldn't be deeper than the macroexpansion done by the byte-compiler
(it's basically the exact same macroexpansion in both cases), but
because it happens earlier it's suffers more often of things like
"macroexp.el is not yet byte-compiled".
These macroexpansion failures should only be warnings, so do
they prevent building Emacs?
If you can reproduce them, can you try to bump max-lisp-eval-depth a bit
higher to see if it solves the problem?
