+
+ Work around portability problem on Solaris 10: flex-generated
+ files include <stdio.h> before <config.h>, which messes up
+ because the latter defines __EXTENSIONS__. Address the problem
+ by creating two new little files that include <config.h> first,
+ then include the flex-generated files. Rewrite everyone else
+ to include <config.h> first, as well.
+ * lib/timevar.c: Always include "config.h".
+ * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with
+ scan-gram-c.c, and scan-skel.l with scan-skel-c.c.
+ (EXTRA_bison_SOURCES): New macro.
+ * src/scan-gram-c.c, src/scan-skel-c.c: New files.
+ * src/system.h: Don't include config.h.
+ * src/LR0.c: Include <config.h> first.

+ (current_lhs, current_lhs_location): Now static.
+ (current_assoc): Remove unused variable.
+
+ Cleanups so that Bison-generated parsers have less lint.
+ * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
+ Prepend /*ARGSUSED*/, for lint's sake.
+ * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
+ definition if 'lint' is defined.
+ (YYID): New macro (or function, if lint).
+ All uses of /*CONSTCOND*/0 replaced by YYID(0).
+ * data/yacc.c: Likewise.
+ * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):

+ Use YYID(0) rather than 0, for lint.
+ (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
+ (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
+
+2005-12-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/glr-regression.at

+ Close memory leak reported by twlevo.
+
+2005-12-06 "Joel E. Denny" <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyprocessOneStack, yyparse): Synchronize the shift for

+ (yyparse): Iterate another stack in order to call user destructors.
+ * tests/glr-regression.at (No users destructors if stack 0 deleted):
+ New test case.
+ (Duplicated user destructor for lookahead): This test now is expected
+ to succeed.
+
+2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Document the following change.
+ * data/yacc.c: Say "parser skeleton" rather than "file", since
+ it's no longer just a file.
+ * data/glr.c: Grant a special exception for C GLR parsers, that
+ reads like the already-existing exception for C LALR(1) parsers.
+ * data/glr.cc: Likewise.
+ * data/lalr1.cc: Likewise.
+ * data/location.cc: Likewise.
+ * data/yacc.c: Reword the "written by" statement to clarify that

+ * data/glr.c: Written by Paul Hilfinger.
+ * data/glr.cc: Written by Akim Demaille.
+ * data/lalr1.cc: Likewise.
+
+2005-11-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
+ Fix typos in previous change that broke 'make check'.
+ YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
+ supported in C.
+ * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
+ Don't check NUM-STDERR-LINES, since the output format is fluctuating.
+ We can revert this once things settle down.
+
+ * src/conflicts.c (conflicts_print): Don't print file name twice
+ when %expect fails because there were no conflicts.
+ * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
+ change.
+ * tests/conflicts.at (%expect not enough, %expect too much):
+ (%expect with reduce conflicts): Adjust to new behavior.

+ Display values and locations.
+ * data/yacc.c (yy_reduce_print): Likewise.
+ (YY_REDUCE_PRINT): Adjust to pass the required arguments.

+
+2005-11-14 Akim Demaille <akim@epita.fr>
+
+ * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
+ from 1 to N, while values and location start at 0.
+ (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
+
+2005-11-14 Akim Demaille <akim@epita.fr>
+
+ * data/glr.c (yy_reduce_print): Fix the $ number.
+
+2005-11-14 Akim Demaille <akim@epita.fr>

+ compatibility.
+ * doc/bison.texinfo (Initial Action Decl): Use initialize.
+
+2005-11-12 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: Move the body of the ctor and dtor into the
+ parser file (instead of the header).
+ Wrap the implementations in a "namespace yy".
+
+2005-11-12 Akim Demaille <akim@epita.fr>
+
+ Have glr.c include its header file when created.
+ * data/glr.c (b4_shared_declarations): New.
+ Output them verbatim in the parser if !%defines, otherwise
+ output then in the header file, and include it instead.
+
+2005-11-11 Akim Demaille <akim@epita.fr>
+
+ * data/glr.c: Comment changes.
+
+2005-11-11 Akim Demaille <akim@epita.fr>

+
+2005-11-09 Albert Chin-A-Young <china@thewrittenword.com>

+ New test.
+
+2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap (cleanup_gnulib): New function. Use it to clean up
