Follow-up Comment #4, bug #46063 (project octave):
I think there is something screwy with the DOCSTRING build as well. If you
can narrow it down to something repeatable I'd file a new bug report about
that.
The issue in this report is that make shouldn't need to call the
move-if-change rule twice on the same file.
I think it is related to the use of BUILT_SOURCES. For example, when I run
make -j1 V=1 |& tee mymake.log
The first file that gets built is defaults.h using move-if-change. A whole
bunch of these other BUILT_SOURCES get constructed and then this:
run-octave is unchanged
rm -f bits/stl_algo.h
make all-recursive
make[1]: Entering directory '/home/rik/wip/Projects_Mine/octave-dev'
Making all in libgnu
make[2]: Entering directory '/home/rik/wip/Projects_Mine/octave-dev/libgnu'
make all-recursive
make[3]: Entering directory '/home/rik/wip/Projects_Mine/octave-dev/libgnu'
make[4]: Entering directory '/home/rik/wip/Projects_Mine/octave-dev/libgnu'
make[4]: Nothing to be done for 'all-am'.
make[4]: Leaving directory '/home/rik/wip/Projects_Mine/octave-dev/libgnu'
make[3]: Leaving directory '/home/rik/wip/Projects_Mine/octave-dev/libgnu'
make[2]: Leaving directory '/home/rik/wip/Projects_Mine/octave-dev/libgnu'
make[2]: Entering directory '/home/rik/wip/Projects_Mine/octave-dev'
/bin/sed < libinterp/corefcn/defaults.in.h > libinterp/corefcn/defaults.h-t -
It would appear that it finishes up the last of the BUILT_SOURCES and then
executes 'make all-recursive'. This starts with the directories mentioned in
SUBDIRS, only libgnu these days, and then changes to the top-level directory
and starts building all of the BUILT_SOURCES again.
One way out of this, I imagine, would be to ditch SUBDIRS completely and have
just a single Makefile. But this means somehow creating a module.mk file for
the libgnu directory.
Just for grins, I commented out SUBDIRS. It isn't strictly necessary after my
changeset today:

summary: Makefile.am: Add libgnu.la to BUILT_SOURCES to generate it early
(partial fix bug #45578).
Octave builds just fine, but it still uses the move-if-change rule twice on
lots of files.
