## The GNU Make "vpath" directive continues this tradition, but at

## Compile, dump, and make sure all .elc files are up-to-date.

## NOTE NOTE NOTE: There appears to be a fundamental but non-obvious
## difference between the way that standard `make', GNU Make, and `nmake'
## handle dependencies, and this means we have to write the dependencies in
## Makefile.in.in and xemacs.mak differently.  To illustrate this, consider
## the following first:

##.PHONY: all (`make' only)
## all: test.exe
##
##.PHONY: FRC.test.c (`make' only)
##FRC.test.c:
##
##test.c: FRC.test.c
##	if test ! -f foo ; then touch test.c; fi (`make' only)
##	if not exist foo touch test.c (`nmake' only)
##
##test.obj: test.c
##	touch test.obj
##
##test.exe: test.obj
##	touch test.exe

## (GNU Make doesn't need the .PHONY declarations, but evidently some versions
## of `make' do.  nmake doesn't need them and doesn't allow them, either.)

## Running `make' rebuilds test.exe only if `foo' doesn't exist.
## Running `nmake -f Makefile' rebuilds it regardless.

## Both conclude that test.c needs to be rebuilt since its dependent is
## non-existent.  But `make' recalculates its dependencies after running
## the commands for test.c, and notices that test.c hasn't changed, and
## thus test.obj and test.exe are up-to-date.  `nmake' doesn't.

## On the other hand, consider the following:

##.PHONY: all (`make' only)
##all: check-foo test.exe
##
##.PHONY: check-foo (`make' only)
##check-foo:
##	if test ! -f foo; then touch test.c; fi (`make' only)
##	if not exist foo touch test.c (`nmake' only)
##
##test.c:
##	touch test.c
##
##test.obj: test.c
##	touch test.obj
##
##test.exe: test.c test.obj
##	touch test.exe
##

## Running `nmake -f Makefile' (and `GNU make') rebuilds test.exe only if
## `foo' doesn't exist.
## Running some versions of non-GNU `make' does nothing at all once test.c,
## test.obj and test.exe all exist.

## It appears that `nmake' doesn't check dependencies for test.exe until it
## actually needs to be rebuilt, so this "sideways" dependency script
## works.  GNU make evidently recalculates *all* dependencies after each
## command so has no problem, either.  But some makes apparently calculate
## all dependencies at startup and then, after executing a command to build
## a dependency, only recheck relationships involving that particular
## dependency.

## In XEmacs-land, the above situation exists wrt the `NEEDTODUMP'
## dependency, recalculated by `update-elc.el'.  Thus, Makefile.in.in must
## use the method #1 above, and nmake must use method #2.
