* src/parse-gram.y: Use the location of the whole definition to record
the location of a %define variable, instead of just the name of the
variable.
Adjust tests.
This improves readability. This is also what gcc does.
* NEWS: Document this change.
* src/complain.c (complain_at): Prefix all errors with "error: ".
(complain_at_indent, warn_at_indent): Do not prefix the context
information of errors, which are basically just indented errors.
* tests/conflicts.at, tests/glr-regression.at, tests/input.at,
tests/named-refs.at, tests/output.at, tests/push.at,
tests/regression.at, tests/skeletons.at: Apply this change.
Signed-off-by: Akim Demaille <akim@lrde.epita.fr>
* tests/push.at: Remove "Push Parsing: " from test group titles
because these are already under the banner "Push Parsing Tests".
(cherry picked from commit 00d80a9ced)
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_grammar): 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.

Resolution): Update use.

* data/yacc.c: Clean up whitespace in the output a little.
(yypstate_allocated): Define for impure push parsers regardless of
whether the pull interface is also requested.
* tests/push.at (Push Parsing: Multiple impure instances): Extend to
check impure push parsers without the pull interface.
* data/yacc.c (yypstate_new): Don't try to invoke yyerror since
yyerror takes arguments specified by %parse-param while yypstate_new
does not.
* doc/bison.texinfo (Parser Create Function): Document that
yypstate_new returns 0 for multiple impure parser instances.
* tests/push.at (Push Parsing: Multiple impure instances): Update
expected stderr output.

BISON_TEST_XML=1.
(AT_BISON_CHECK_NO_XML): Likewise, but skip XML checks.
(AT_BISON_CHECK_XML): New.

* data/c.m4 (b4_identification): Depend on individual skeletons to

parsing requests here...

b4_use_push_pull_flag or the %define variable push_pull is set. This
will go away when we mv push.c yacc.c.
* data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that

reported anyway.

already 1. Otherwise, set it to 1.

* THANKS: Add Brandon Lucia.
* data/push.c (yypstate_delete): Free the stack if it was reallocated
