Add check for leaked parent RHS values. * data/glr.c (yydestroyGLRState): In debugging output, distinguish between an unresolved state (non-empty chain of semantic options) and an incomplete one (signaled by an empty chain).

Document the interface. (yyresolveAction): If resolving any of the RHS states fails, destroy them all rather than leaking them. Thus, as long as user actions are written to clean up the RHS correctly, yyresolveAction always cleans up the RHS of a semantic option. Document the interface.

Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I 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.

Fix some porting glitches found by Nelson H. F. Beebe. * 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.

Minor fixups to get 'make maintainer-check' to work. * 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'.

* doc/bison.texinfo: Fix some typos. (GLR Semantic Actions): New subsection discussing special considerations because GLR semantic actions might be deferred. (Actions): Mention look-ahead usage of yylval. (Actions and Locations): Mention look-ahead usage of yylloc. (Special Features for Use in Actions): Add YYEOF entry and mention it in the yychar entry. In the yychar entry, remove mention of the local yychar case (pure parser) since this is irrelevant information when writing semantic actions and since it's already discussed in Bison Symbols' where yychar is otherwise described as an external variable. In the yychar entry, don't call it the current' look-ahead since it isn't when semantic actions are deferred. In the yychar and yyclearin entries, add note about deferred semantic actions. Add yylloc and yylval entries discussing look-ahead usage. (Look-Ahead Tokens): When discussing yychar, don't call it the current' look-ahead, and do mention yylval and yylloc. (Error Recovery): Cross-reference Action Features' when mentioning yyclearin. (Bison Symbols): In the yychar entry, don't call it the `current' look-ahead. In the yylloc and yylval entries, mention look-ahead usage.
