In reply to two of your emails, sorry:

+    if dependencies:
+        print(f"Package {pkg} depends on:")
+        for d in dependencies:
+            print(f" -> {d}")
+

I wouldn't add this. It's only useful some of the time, not in normal
usage, and anyway "pactree" does the same thing better.

def gather_deps(deps, arch, directory):

-    os.mkdir(arch)
+    if not os.path.exists(arch):
+        os.mkdir(arch)
     os.chdir(arch)

This is wrong, I think. IIRC, my script crashes out at this point if
"arch" exists. This is needed, otherwise I could run build-dep-zips.py
twice at different times and both old and new dependencies would get
added. This forces cleanliness.

+              'bin/msg*.exe', # No tools to manipulate gettext catalogues
+              'bin/*gettext.exe'
+    ]

This list would need to go near the front, so we have a clean
configuration section. It also displays the key problem -- it's really
long and non obvious so a maintenance burden

If we just did a few big top level directories, would that not solve all
the problems.

I am vaguely curious what it looks like in Spanish. I thought the output
was fairly mechanistic.


- Since we are pulling in compression utilities, we may just as well tell the
  configuration to compress the *.el files. Windows is the only platform where
  this does not happen

No, because I generate the no-deps version first, then add the deps. The
-no-deps version doesn't have the compression utilities. Of course, we
do not need the *.el files at all.


  a) Is there a way to test the resulting standalone distribution to
  verify that Emacs is running properly?

No. The only testing I do is to start Emacs and see if it starts and
looks okay (literally looks okay -- the icons can get broken). The lack
of a test suite that I can run is what keeps me cautious, especially as
I don't use this build. I wrote a robot testing framework for
org-drill.el; we could do something similar for testing this version of
Emacs.


  b) I realized that Cairo is pulled in as a dependency, but Emacs is
  built without support for Cairo. Is this intentional?

No, it will be a transitive dependency of something. pactree will
reveal!
