Commit af000bab11 ("doc: work around
Texinfo 6.7 bug"), published in 3.4.91, added a dependency on the
"all" target.
This is a super bad idea, since "make all" will run this
target *before* "all", which builds bison. It turns out that this new
dependency actually needed bison to be built. So all the regular
process (i) build $(BUILT_SOURCES) and then (ii) build bison, was
wrecked since some of the $(BUILT_SOURCES) depended on bison...
It was "easy" to see in the logs of "make V=1" because we were
building bison files (such as src/files.o) *before* displaying the
banner for "all-recursive". With this fix, we finally get again the
proper sequence:
rm -f examples/c/reccalc/scan.stamp examples/c/reccalc/scan.stamp.tmp
/opt/local/libexec/gnubin/mkdir -p examples/c/reccalc
touch examples/c/reccalc/scan.stamp.tmp
flex -oexamples/c/reccalc/scan.c --header=examples/c/reccalc/scan.h ./examples/c/reccalc/scan.l
mv examples/c/reccalc/scan.stamp.tmp examples/c/reccalc/scan.stamp
rm -f lib/fcntl.h-t lib/fcntl.h && \
{ echo '/* DO NOT EDIT! GENERATED AUTOMATICALLY! */'; \
...
} > lib/fcntl.h-t && \
mv lib/fcntl.h-t lib/fcntl.h
...
mv -f lib/alloca.h-t lib/alloca.h
make all-recursive

* doc/local.mk (all): Rename as...
(all-local): this.
So that we don't compete with BUILT_SOURCES.
* doc/bison.texi (Tokens from Literals): Move to code using
%token-table to...
(Decl Summary: %token-table): here.
* data/skeletons/bison.m4: Implement mutual exclusion.
* tests/input.at: Check it.

This is very easy to do, thanks to work by Bruno Haible in gnulib.
See "Supporting Relocation" in gnulib's documentation.
* bootstrap.conf: We need relocatable-prog and relocatable-script (for yacc).
* src/yacc.in: New.
* configure.ac, src/local.mk: Instantiate it.
* src/main.c, src/output.c (main, pkgdatadir): Use relocatable2.
* doc/bison.texi (FAQ): Document it.
The "Report translation bugs to..." part of --help is issued only on
glibc systems. So if the tarball is not wrapped on such a system, and
used on such a system (or the converse), then bison.help will differ
on the user's system, and help2man will be called to update bison.1.
But help2man should not be a requirement.
Reported by Alexandre Duret-Lutz.
* doc/local.mk (doc/bison.help): Remove the possible doc about
translation bugs.
Pass LC_ALL=C, as reported in src/getargs.c's usage().
(doc/cross-options.texi): Use bison.help instead of calling bison
--help.
Now that distcheck no longer fails (see previous commit), let's
address the shortcomings.
* Makefile.am (CLEANDIRS, clean-local): New.
* doc/local.mk, examples/calc++/local.mk, examples/local.mk,
* examples/mfcalc/local.mk, examples/rpcalc/local.mk,
* src/local.mk
(CLEANDIRS): Get rid of Apple's *.dSYM directories.
(CLEANFILES): Get rid of *.output files.
* examples/variant-11.yy, examples/variant.yy: Don't generate
any of the auxiliary files (location.hh and the like).
* configure.ac (ENABLE_YACC): New conditional.
(YACC_SCRIPT, YACC_LIBRARY): Remove.
* lib/local.mk, src/local.mk: Use the former instead of the latter.
* doc/local.mk: Use ENABLE_YACC to avoid installing yacc.1.
We don't ship the *.txt files that are used to build the info
file.
Reported by Colin Daley.
* doc/figs/example.txt: New.
* doc/local.mk (bison.info): Depend on the txt files.
And ship them.

Bison uses "/usr/bin/perl" or "perl" in several places, and it does
not appear to be a problem. But, at least to make it simpler to
change PERL on the make command line, check for perl in configure.
* configure.ac (PERL): New.
* doc/Doxyfile.in, doc/local.mk, examples/local.mk,
* tests/bison.in: Use it.
For some reason it seems that texi2dvi -o no longer forces --clean
mode, so we have stray TeX compilation files staying in top_builddir
since TeX is run from there.
While at it, upgrade the generation of the (completely obsolete)
reference card. Target PDF.
* doc/local.mk (TEXI2DVI): Pass --build-dir.
(CLEANDIRS): More accurate.
(doc/refcard.dvi): Replace with...
(doc/refcard.pdf): this.
Adjust dependencies.
This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
Some of our targets use "bison --help", but they can't depend on
"bison" itself (to avoid additional requirements on the user), so
they used to call "make src/bison" in the commands. Then
concurrent builds may fail: one make might be aiming one of its
jobs at compiling src/bison, and another job at generating the man
page. If the latter is faster than the former, then we have two
makes that concurrently try to compile src/bison.
This might also be a more convincing explanation for the failure
described in the patch "build: fix paths".
* Makefile.am (SUFFIXES): Initialize.
* build-aux/move-if-change: New, symlink to gnulib's.
* build-aux/local.mk: Ship it.
* doc/common.x: Remove, merged into...
* doc/bison.x: here.
* doc/local.mk (doc/bison.help): New.
($(CROSS_OPTIONS_TEXI)): Depend on it.
Use src/bison.
(.x.1): Replace with...
(doc/bison.1): this explicit, simpler, target.
(common_dep): Remove, inlined where appropriate.
(SUFFIXES, PREPATH): Remove, unused.
When using $(top_builddir) inconsistently, Make (including GNU
Make) is sometimes confused. As a result it may want to build
lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
file, different names) concurrently, which, amusingly enough,
might end with:
ranlib lib/libbison.a
ranlib lib/libbison.a
make[2]: *** [lib/libbison.a] Segmentation fault
on OS X.
* doc/local.mk, src/local.mk: Do not use $(top_builddir) when not
needed.
