+ * tests/cxx-type.at: Reformat whitespace with tabs.
+ (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo

+
+ Let glr.cc catch up with symbol_value_print.
+ * data/glr.cc (b4_yysymprint_generate): Replace by...

+2005-12-28 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/location.h (boundary): Note that a line or column equal
+ to INT_MAX indicates an overflow.

+ (rule_length_overflow, increment_rule_length, add_column_width):
+ New functions.
+ (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):

+ values, check that the warning is issued.
+
+2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Improve wording for unused-value warnings.
+
+2005-12-22 Akim Demaille <akim@epita.fr>

+2005-12-22 Akim Demaille <akim@epita.fr>
+
+ * NEWS: Warn about unused values.

+
+ Undo 2005-12-01 tentative license wording change. The wording is
+ still being reviewed by the lawyers, and we don't want to wait for
+ them before publishing a test release. For now, revert to the
+ previous wording.
+ * NEWS: Undo 2005-12-01 change.
+ * data/glr.c: Revert to previous license wording.
+ * data/glr.cc: Likewise.
+ * data/lalr1.cc: Likewise.

+ * data/lalr1.cc: Likewise.
+ * data/yacc.c: Likewise.
+ * data/yacc.c: Reformat comments slightly.
+ * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,

+2005-12-21 Joel E. Denny <address@hidden>
+
+ * tests/cxx-type.at: Construct a tree, count the parents of shared
+ nodes, and free each node once and only once. Previously, the memory
+ for semantic values was leaked instead.
+
+2005-12-21 Joel E. Denny <address@hidden>
+
+ * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
+ (yylval, yylloc): If pure, #define to yystackp->yyval and
+ yystackp->yyloc similar to yychar and yynerrs.
+ (yyparse): If pure, remove local yylval and yylloc. Add local
+ yystackp to accommodate pure definitions of yylval and yylloc.
+ (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
+ yylvalp and yyllocp to &yylval and &yylloc.
+ (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
+ namespace. Previously, nerrs and char were missing, but lval and lloc
+ weren't necessary.
+ (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
+ yylvalp and yyllocp parameters since, if pure, these are now always
+ accessible through yystackp. If not pure, they are still accessible
+ globally.
+ * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
+ `if (YYID (N))' to pacify lint.
+
+2005-12-21 Akim Demaille <akim@epita.fr>
+
+ YYACCEPT, YYERROR, and YYABORT, as user actions, should not
+ destroy the RHS symbols of a rule.
+ * data/yacc.c (yylen): Initialize to 0.
+ Keep its value to the number of items to possibly shift.
+ In particular, a regular successful parse that ends on YYFINAL by
+ a (internal) YYACCEPT must not have yylen != 0.
+ (yyerrorlab, yyreturn): Pop the RHS.
+ Reorder a bit to emphasize the `shifting' bits of code.
+ (YYPOPSTACK): Now accept a number of items to pop.
+ * data/lalr1.cc: Likewise.
+ * data/glr.c: Formatting changes.
+ Use goto instead of fall through.
+ * doc/bison.texinfo (Destructor Decl): Complete.
+
+2005-12-20 Juan Manuel Guerrero <juan.guerrero@gmx.de>
+
+ * Makefile.am: DJGPP specific files added to EXTRA_DIST.
+ * djgpp/Makefile.maint: Fix PACKAGE variable computation.
+ * djgpp/config.bat: Replace every occurence of the file name
+ scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
+ c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
+ * djgpp/config.sed: Replace every occurence of the file name
+ scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
+ c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
+ * djgpp/djunpack.bat: DJGPP specific file.
+ * djgpp/fnchange.lst: DJGPP specific file.
+ * djgpp/README.in: Add new information about how to unpack the bison
+ source on MSDOS and other systems which have 8.3 file name restrictions
+ using djunpack.bat and fnchange.lst.
+
