That makes things much more sensible for me, although problems remain.
Also note my followup to that.
It was without that patch. Here are the same experiments performed with
it. There are still four binary variables:
1) Build inside the source tree vs. build outside the source tree.
2) An XEmacs 21.2.41 with Stephen's patch applied (which I call
"vanilla" below) vs. an XEmacs 21.2.41 with Stephen's patch AND
this patch applied (which I call "patched" below):
<URL:http://www.xemacs.org/list-archives/xemacs-beta/200012/msg00170.html>;.
Between builds, I completely removed the source tree, and then
reunpacked the XEmacs 21.2.41 tarball to be sure there was no
poisoning of one test by another.
3) Building with no previously built XEmacs installed vs. building
with a previous build of 21.2.41 installed. I am using a prefix of
/usr/local/test for this so that my XEmacs 21.1 won't get in the
way.
4) Run in place vs. run in the install location.
For each of the 16 possible combinations of these variables, I report on
the values of 3 Lisp variables related to modules. For sanity's sake, I
also checked doc-directory and exec-directory, the only other variables
that are set with paths-find-architecture-directory. Those two
variables are correct in every experiment (i.e., set to the appropriate
source directory for run-in-place, and the appropriate install directory
for the installed XEmacs), so I don't show them below.
The results are shown below. Even though variables #1 and #3 should not
be affecting the outcome, they are. Also, although #4 should affect the
outcome, it isn't affecting it in the right way. Comparison with the
results from the previous experiments shows that experiments 2, 6, 10,
12, and 14 gave better results with Stephen's patch, but experiment 11
gave worse results with that patch! Looking at the effects of the
second patch below, we see that it improves the results for experiments
2 (compare 6), 3 (compare 7 -- although it's still wrong), and 4
(compare 8), it doesn't make the results of any experiments worse, and
it has no effect if Stephen's patch is also applied.

I've worked on tracking this down a little more. I think I've found the
source of the inconsistencies, but I need a little information to be
sure.
1) The function paths-find-emacs-roots, if given an invocation-directory
argument that is outside of the XEmacs source tree, returns the root
of the build tree, but NOT the root of the source tree. Is that
desirable behavior? That is, would it be wrong if it returned the
list (build-tree source-tree)?
2) When building outside of the source tree, configure sets up build
directories and links to things inside the source tree. However, it
neither creates a "modules" directory nor links to the one in the
source tree. Is that wrong?
If the answers are "yes" and "no", respectively, then the results of
experiment 1 (from my previous message) are actually correct. In that
case, module-load-path *should* be nil, since there is no directory
named "modules" in the build tree, and XEmacs should not be looking in
the source tree.

Yes. Otherwise it would confound an existing in-source build with a
separate build directory build. This is not a problem for Lisp and
Info (we hope), thus the links, but in principle the build tree should
contain its own copy of all generated files.

Ie, yes.
Right, Michael?
2) When building outside of the source tree, configure sets up build
directories and links to things inside the source tree. However, it
neither creates a "modules" directory nor links to the one in the
source tree. Is that wrong?
Yes. It should either copy the modules tree or link to it. Martin
says "XEmacs knows everything the modules needs to know, ask XEmacs
about configuration stuff." If that's true, then it's quite likely
that the modules will be XEmacs-build-dependent, and the tree should
be _copied_.
If modules should be independent of the xemacs binary build, then the
tree should be _linked_ and we should be looking for dependencies on
the build process, considering them to be bugs.
