 584 ### Bootstrapping.
 585
 586 ## Bootstrapping right is difficult because of the circular dependencies.
 587 ## Furthermore, we have to deal with the fact that many compilation targets
 588 ## such as loaddefs.el or *.elc can typically be produced by any old
 589 ## Emacs executable, so we would like to avoid rebuilding them whenever
 590 ## we build a new Emacs executable.
 591 ## To solve the circularity, we use 2 different Emacs executables,
 592 ## "emacs" is the main target and "bootstrap-emacs" is the one used
 593 ## to build the *.elc and loaddefs.el files.
 594 ## To solve the freshness issue, we used to use a third file "witness-emacs"
 595 ## which was used to witness the fact that there is a bootstrap-emacs
 596 ## executable, and then have dependencies on witness-emacs rather than
 597 ## bootstrap-emacs, but that lead to problems in parallel builds (because
 598 ## witness-emacs needed to be free from dependencies (to avoid rebuilding
 599 ## it), so it was compiled in parallel, leading typically to having 2
 600 ## processes dumping bootstrap-emacs at the same time).
 601 ## So instead, we replace the witness-emacs dependencies by conditional
 602 ## bootstrap-dependencies (via $(BOOTSTRAPEMACS)).  Of course, since we do
 603 ## not want to rely on GNU Make features, we have to rely on an external
 604 ## script to do the conditional part of the dependency
 605 ## (i.e. see the $(SUBDIR) rule ../Makefile.in).
 606
 607 .SUFFIXES: .elc .el
 608
 609 ## These suffix rules do not allow additional dependencies, sadly, so
 610 ## instead of adding a $(BOOTSTRAPEMACS) dependency here, we add it
 611 ## separately below.
 612 ## With GNU Make, we would just say "%.el : %.elc $(BOOTSTRAPEMACS)"
 613 .el.elc:
 614         @cd ../lisp; $(MAKE) $(MFLAGS) compile-onefile \
 615                              THEFILE=$< EMACS=$(bootstrap_exe)
 616
 617 ## Since the .el.elc rule cannot specify an extra dependency, we do it here.
 618 $(lisp): $(BOOTSTRAPEMACS)
