 554 ### Bootstrapping.
 555
 556 ## Bootstrapping right is difficult because of the circular dependencies.
 557 ## Furthermore, we have to deal with the fact that many compilation targets
 558 ## such as loaddefs.el or *.elc can typically be produced by any old
 559 ## Emacs executable, so we would like to avoid rebuilding them whenever
 560 ## we build a new Emacs executable.
 561 ## To solve the circularity, we use 2 different Emacs executables,
 562 ## "emacs" is the main target and "bootstrap-emacs" is the one used
 563 ## to build the *.elc and loaddefs.el files.
 564 ## To solve the freshness issue, we used to use a third file "witness-emacs"
 565 ## which was used to witness the fact that there is a bootstrap-emacs
 566 ## executable, and then have dependencies on witness-emacs rather than
 567 ## bootstrap-emacs, but that lead to problems in parallel builds (because
 568 ## witness-emacs needed to be free from dependencies (to avoid rebuilding
 569 ## it), so it was compiled in parallel, leading typically to having 2
 570 ## processes dumping bootstrap-emacs at the same time).
 571 ## So instead, we replace the witness-emacs dependencies by conditional
 572 ## bootstrap-dependencies (via $(BOOTSTRAPEMACS)).  Of course, since we do
 573 ## not want to rely on GNU Make features, we have to rely on an external
 574 ## script to do the conditional part of the dependency
 575 ## (i.e. see the $(SUBDIR) rule ../Makefile.in).
 576
 577 .SUFFIXES: .elc .el
 578
 579 ## These suffix rules do not allow additional dependencies, sadly, so
 580 ## instead of adding a $(BOOTSTRAPEMACS) dependency here, we add it
 581 ## separately below.
 582 ## With GNU Make, we would just say "%.el : %.elc $(BOOTSTRAPEMACS)"
 583 .el.elc:
 584         @cd ../lisp; $(MAKE) $(MFLAGS) compile-onefile \
 585                              THEFILE=$< EMACS=$(bootstrap_exe)
 586
 587 ## Since the .el.elc rule cannot specify an extra dependency, we do it here.
