I took the easy way out and ignored byte-compilation. :-) So, what was
working was actually Emacs Lisp text, as is. -- I, too, noticed
that the Makefiles are referring to versions of Emacs in specific
locations and decided to ignore this part for now. Should have said so.

Things I remember. I have used the sources for workbench style
experimentation, no complete install done. I am reproducing,
at the dashes below, what I remember only to point out where
there might be sources of confusion, or of going astray.
A bird's-eye view of the overall organization of the sources
and the build process will, I think, be quite helpful. I have
started a few notes, not implying that they are generally
useful, or up to date. They reflect what I have learned.
Texinfo appended below. Maybe some of the comments in the
Wisent/Elisp files can be reworked into this overview?
1. steps taken:
- Start, in org.emacs.ada-mode.stephe-1, find a README.txt
or INSTALL.txt, or a Makefile; experiment; also look around, and
guess that the files ending with ".wy" are important (i.e.,
demonstrate lack of knowledge of semantic/wisent, and its use
with OpenToken).
- Follow the pointer to build/wisi
- see what $(make -n) gives, learn about wisi-generate.exe
- Switch projects to opentoken.
- { use the source from the Web site, which has now been patched]
- { or find the proper branch in VC (is it org.opentoken.stephe?).
- Again, learn from README.txt.
- build wisi-generate.exe and keep it.
2. bird's-eye view:
@section Producing Ada Mode's Parsers From Scratch
For its indentation functions, Ada Mode ultimately uses parsers
written for @xref{Wisent}. Two parsers are provided. One is for Ada
source text, the other is for GNAT project files. Wisent grammars of
either will be found in @file{ada-grammar.wy}, and
@file{gpr-grammar.wy}, respectively.
To produce Emacs Lisp text from these descriptions, you would run the
program @command{wisi-generate.exe}. The program is written in Ada
and uses the
@uref{http://www.stephe-leake.org/ada/opentoken.html,OpenToken}
library adapted for the purposes of Ada Mode. Its input is a
@samp{.wy} file, its output is Emacs Lisp, @pxref{wisi-user-manual}.
Two makefiles have been set up for compiling, and properly invoking
@command{wisi-generate.exe}, respectively. One, @file{...}, is part
of the accompanying distribution of OpenToken. The other,
@file{build/wisi/Makefile}, is part of Ada Mode proper.
