## such as loaddefs.el or *.elc can typically be produced by any old
## Emacs executable, so we would like to avoid rebuilding them whenever
## we build a new Emacs executable.
+##
+## (In other words, changing a single file src/foo.c would force
+## dumping a new bootstrap-emacs, then re-byte-compiling all preloaded
+## elisp files, and only then dump the actual src/emacs, which is not
+## wrong, but is overkill in 99.99% of the cases.)
+##
## To solve the circularity, we use 2 different Emacs executables,
## "emacs" is the main target and "bootstrap-emacs" is the one used
## to build the *.elc and loaddefs.el files.
-## To solve the freshness issue, we used to use a third file "witness-emacs"
-## which was used to witness the fact that there is a bootstrap-emacs
-## executable, and then have dependencies on witness-emacs rather than
-## bootstrap-emacs, but that lead to problems in parallel builds (because
-## witness-emacs needed to be free from dependencies (to avoid rebuilding
-## it), so it was compiled in parallel, leading typically to having 2
-## processes dumping bootstrap-emacs at the same time).
-## So instead, we replace the witness-emacs dependencies by conditional
-## bootstrap-dependencies (via $(BOOTSTRAPEMACS)). Of course, since we do
