Some consistency checks on symbols are performed after all the
symbols were read, by an iteration over the symbol table. This
traversal is nondeterministic, which can be a problem for test
cases.
Avoid this.
Addresses another form of nondeterminism reported by Joel E. Denny.

* tests/input.at (Numbered tokens): Split the hexadecimal/decimal
test in two.
Use different file names for the three tests to make the
maintenance easier.
* gnulib: Update to latest.
* lib/.cvsignore, lib/.gitignore, m4/.cvsignore,
* m4/.gitignore: Regen.
* src/symtab.c (symbol_from_uniqstr, semantic_type_from_uniqstr):
Call xalloc_die on hash_insert failures.
Requested by the new __warn_unused_result__ attribute of
hash_insert.
* src/scan-gram.l ({id}): Also accept dashes after the initial
letter.
({directive}): Use {id}.
* src/parse-gram.y: Comment and formatting changes.
* doc/bison.texinfo (Symbols): Adjust the lexical definitions of
symbols.
* src/complain.h, src/complain.c (yacc_at): New.
* src/symtab.c (symbol_new): Use yacc_at to report inappropriate
symbol names.
* src/output.c (token_definitions_output): Do not #define token
names with dashes.
(cherry picked from commit 4f646c3794)
Conflicts:
data/bison.m4
src/parse-gram.y
* tests/local.at (AT_MATCHES_CHECK): New.
Based on Perl instead of Sed. Sed has too many portability
pitfalls, not ever Sed is GNU Sed.
* tests/actions.at (Fix user actions without a trailing semicolon):
Use it.
(cherry picked from commit 6617622c9a)
* src/getargs.h, src/getargs.c (trace_muscle): New.
(trace_types, trace_args): Support it.
* src/output.c (output_skeleton): Use it.
(cherry picked from commit 5263bea9f7)
* src/getargs.h, src/getargs.c (skeleton_arg, language_argmatch):
The location argument is now mandatory.
Adjust all dependencies.
(getargs): Use command_line_location.
* src/getargs.c (quotearg.h, muscle_tab.h): Include.
(getargs): Define file_name.
* src/main.c (main): Initialize muscle_tab before calling
getargs.
* src/muscle_tab.c (muscle_init): No longer define file_name, as
its value is not available yet.
* build-aux/cross-options.pl: The argument ends at the first
space, not the first non-symbol character.
Use @var for each word appearing the argument description.
(cherry picked from commit 74eae918c3)
GCC 4.3 now warns about "a || b && c" and asks for explicit
parentheses.
Reported by Alexandre Duret-Lutz.
* data/location.cc: Update copyright years.
(Position::operator==): Use parens to make precedence explicit.
Compare lines and columns first, as they are more likely to be
different, and they are faster to compare.
Grep on Solaris does not support -q.
Reported by Summum Bonum.
* NEWS: Add a stub for 2.4.2.
* THANKS: Add Summum Bonum.
* tests/atlocal.in (EGREP): New.
(CC, CXX, XSLTPROC): Make it possible to override them via
envvars.
* tests/java.at: Use $EGREP instead of egrep.
Use AT_CHECK's ignore instead of grep's -q.
* data/lalr1.cc (debug_stream, set_debug_stream)
(debug_level_type, debug_level, set_debug_level): Don't
declare them when YYDEBUG is not defined.
The implementation are already YYDEBUG-aware.
