 576 ### Bootstrapping.
 577
 578 ## Bootstrapping right is difficult because of the circular dependencies.
 579 ## Furthermore, we have to deal with the fact that many compilation targets
 580 ## such as loaddefs.el or *.elc can typically be produced by any old
 581 ## Emacs executable, so we would like to avoid rebuilding them whenever
 582 ## we build a new Emacs executable.
 583 ## To solve the circularity, we use 2 different Emacs executables,
 584 ## "emacs" is the main target and "bootstrap-emacs" is the one used
 585 ## to build the *.elc and loaddefs.el files.
 586 ## To solve the freshness issue, we used to use a third file "witness-emacs"
 587 ## which was used to witness the fact that there is a bootstrap-emacs
 588 ## executable, and then have dependencies on witness-emacs rather than
 589 ## bootstrap-emacs, but that lead to problems in parallel builds (because
 590 ## witness-emacs needed to be free from dependencies (to avoid rebuilding
 591 ## it), so it was compiled in parallel, leading typically to having 2
 592 ## processes dumping bootstrap-emacs at the same time).
 593 ## So instead, we replace the witness-emacs dependencies by conditional
 594 ## bootstrap-dependencies (via $(BOOTSTRAPEMACS)).  Of course, since we do
 595 ## not want to rely on GNU Make features, we have to rely on an external
 596 ## script to do the conditional part of the dependency
 597 ## (i.e. see the $(SUBDIR) rule ../Makefile.in).
 598
 599 .SUFFIXES: .elc .el
 600
 601 ## These suffix rules do not allow additional dependencies, sadly, so
 602 ## instead of adding a $(BOOTSTRAPEMACS) dependency here, we add it
 603 ## separately below.
 604 ## With GNU Make, we would just say "%.el : %.elc $(BOOTSTRAPEMACS)"
 605 .el.elc:
 606         @cd ../lisp; $(MAKE) $(MFLAGS) compile-onefile \
 607                              THEFILE=$< EMACS=$(bootstrap_exe)
 608
 609 ## Since the .el.elc rule cannot specify an extra dependency, we do it here.
 610 $(lisp): $(BOOTSTRAPEMACS)
