nodist_PROGRAMS, since we don't need to actually compile the
example if we're just doing a plain 'make'. This avoids bothering
the installer unnecessarily about problems due to weird C++
compilers.
influence the parse by changing yychar. To make this easier to fix and
to make glr.c easier to evolve in general, don't maintain yytoken in
parallel with yychar; just compute yytoken when needed.
* tests/glr-regression.at (Incorrect lookahead during deterministic
GLR): Check that setting yychar in a user action has the intended
effect.
* data/glr.c (yyGLRStack): Remove yytokenp member.
(yyclearin): Don't set *yytokenp.
(yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
yychar rather than *yytokenp to determine the current lookahead.
Compute yytoken locally when needed.
(yyparse): Likewise. Remove the local yytoken that yytokenp used to
point to.
* doc/bison.texinfo (Bison Options): Remove stray sentence fragment
after `--report' documentation.
got from <http://bro-ids.org/download.html>. The bug is that
when two actions appeared in succession, the second one was
scanned before the first one was added to the grammar rule
as a midrule action. Bison then output the incorrect warning
"parse.y:905.17-906.36: warning: unused value: $3".
* src/parse-gram.y (BRACED_CODE, action): These are no longer
associated with a value.
(rhs): Don't invoke grammar_current_rule_action_append.
(action): Invoke it here instead.
* src/reader.c (grammar_midrule_action): Now extern.
(grammar_current_rule_action_append): Don't invoke
grammar_midrule_action; that is now the scanner's job.
* src/reader.h (last_string, last_braced_code_loc):
(grammar_midrule_action): New decls.
* src/scan-gram.l (last_string): Now extern, sigh.
(last_braced_code_loc): New extern variable.
(<INITIAL>"{"): Invoke grammar_midrule_action if the current
rule already has an action.
(<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
* tests/input.at (AT_CHECK_UNUSED_VALUES):
Add some tests to check that the above changes fixed the bug.
All used changed. Check whether the symbol has a destructor,
not whether it is typed.
* tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
that the values are still reported as unused. All line numbers
adjusted.
definition of YYLLOC_DEFAULT.
* data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
their arguments.
* data/lalr1.cc: Likewise.
* data/yacc.cc: Likewise.
user can override the types.
(short): #undef, to work around a bug in Pike 7.0.
(yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
(union yyalloc.yyss): Use yytype_int16 rather than short.
All uses changed.
(yysigned_char): Remove.
* src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
(YYTYPE_INT16): New macros, to test the new facility in yacc.c.
* tests/regression.at (Web2c Actions): Adjust to above changes.
to pacify gcc -Wswitch-default.
* src/scan-gram.l (adjust_location): Use a default: break; case
to pacify gcc -Wswitch-default.

(skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
(skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
Move these decls to scan-skel.l, since they don't need to be
visible elsewhere.
* src/scan-skel.l: Accept the above decls.
(skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
is used.
* lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
compilers that don't understand that abort () does not return.
* src/state.c (transitions_to): Likewise.
* m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
that '#include <cstdlib>' works.
* src/system.h (INT8_MIN, INT16_MIN, INT32_MIN, INT8_MAX):
(INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
#undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
for the benefit of some pre-C99 compilers.
* configure.ac: Don't use -Wnested-externs, as it's incompatible
with the new verify.h implementation.
* data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
* data/glr.c (YYUSE): Depend on __GNUC__ as well.
* data/yacc.c (YYUSE): Likewise.
* data/lalr1.cc (yysyntax_error_): YYUSE (yystate).
* lib/subpipe.c (end_of_output_subpipe): The args are unused.
* src/parse-gram.y (declaration): Don't pass a string constant
to a function that expects char *, since GCC might complain
about the constant value.
* src/reader.c (symbol_typed_p): Add parens to pacify GCC.
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval
before #defining them.
* tests/glr-regression.at
(Incorrectly initialized location for empty right-hand side in GLR):
In yyerror, use the msg arg.
(Corrupted semantic options if user action cuts parse):
(Incorrect lookahead during deterministic GLR):
(Incorrect lookahead during nondeterministic GLR):
Don't name a local var 'index'; it shadows string.h's 'index'.
(CVS_LIST): Use build-aux version if available.
(VERSION_REGEXP): New macro.
(syntax-check-rules): Add sc_no_if_have_config_h,
sc_prohibit_assert_without_use, sc_require_config_h,
