LocalWords, since the latter are looked for in the whole document,
while the former are looked for only at its end.
Require american spell checking.
* doc/bison.texinfo (Decl Summary): Document the "lex_symbol" and
"variant" %define variables.
(C++ Semantic Values): Split into...
(C++ Unions, C++ Variants): these.
The latter is new.
(C++ Parser Interface): Fix type names.
Document parser::syntax_error.
Document the fact that locations are not mandatory.
(C++ Scanner Interface): Split into...
(Split Symbols, Complete Symbols): these.
The later is new.
(Calc++ Parsing Driver): Use variants.
Add more comments.
Adjust style.
(Calc++ Parser): Declare all the tokens, no
longer accept raw characters.
Remove %union.
Adjust types and printers.
Remove destructors.
(Calc++ Scanner): Use make_<SYMBOL> functions.
Use strerror in error message.
* NEWS (2.6): Document %param, %lex-param, and %parse-param
changes.
* doc/bison.texinfo: Document that %lex-param and %parse-param
are n-ary.
Changes some examples to demonstrate it.
(Calc++ Parser): Use %param.
Reported by Bill Allombert.
* doc/bison.texinfo: Set fill-column to 76.
(Location Type): Document the use of %initial-action to initialize
yylloc.

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.
Implement, document, and test the replacement of %error-verbose
by %define parse.error "verbose".
* data/bison.m4 (b4_error_verbose_if): Reimplement to track the
values of the parse.error variable.
Make "simple" its default value.
Check the valid values.
* src/parse-gram.y: Use %define parse.error.
(PERCENT_ERROR_VERBOSE): New token.
Support it.
* src/scan-gram.l: Support %error-verbose.
* doc/bison.texinfo (Decl Summary): Replace the documentation of
%define error-verbose by that of %define parse.error.
* NEWS: Document it.
* tests/actions.at, tests/calc.at: Use parse.error instead of
%error-verbose.
Discussed in
http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00033.html
* data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
New.
(b4_percent_define_use): New.
Use it where applicable.
* data/c++.m4: Replace uses of the variable "namespace" by
"api.namespace".
Default the latter to the former.
* doc/bison.texinfo (Decl Summary): Document "namespace" as
obsolete.
Document api.namespace.
Use @samp to document %define uses, keep @code for identifiers.
* NEWS: Likewise.
* tests/c++.at, tests/input.at: Test api.namespace instead of
namespace. (The tests passed with namespace.)
* doc/bison.simple (Decl Summary): Document token.prefix.
(Calc++ Parser): Various fixes.
Formatting changes.
Use token.prefix.
Introduce a macro TOKEN to shorten the code and make it more
readable.
(Calc++ Scanner): Adjust.
* NEWS (Variable token.prefix): New.
For now, just api.push-pull and lr.keep-unreachable-states.
Maintain old names for backward compatibility.
* NEWS (2.5): Document.
* data/c.m4 (b4_identification): Update comment.
* data/yacc.c: Update access.
* doc/bison.texinfo: Update.
* etc/bench.pl.in (bench_push_parser): Update use.
* src/files.c (tr): Move to...
* src/getargs.c, src/getargs.h (tr): ... here because I can't
think of a better place to expose it. My logic is that, for all
uses of tr so far, command-line arguments can be involved, and
getargs.h is already included.
* src/main.c (main): Update access.
* src/muscle_tab.c (muscle_percent_define_insert): Convert old
variable names to new variable names before assigning value.
* src/reader.c (reader): Update setting default.
* tests/calc.at: Update uses.
* tests/conflicts.at (Unreachable States After Conflict
Resolution): Update use.
* tests/input.at (%define enum variables): Update use.
(%define backward compatibility): New test group.
* tests/push.at: Update uses.
* tests/reduce.at: Update uses.
* tests/torture.at: Update uses.
