+
+ * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
+
+ * src/location.h (struct): The file member is a uniqstr.
+ (equal_boundaries): Use UNIQSTR_EQ for comparison.

+
+ Fix bug with non-%union parsers that have printers or destructors,
+ which led to a Bison core dump. Reported by Peter Fales in
+ <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
+
+ * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
+ * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
+ not to our own type.
+ * src/output.c (symbol_destructors_output, symbol_printers_output):
+ Don't assume %union.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
+ AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
+ UNION-FLAG. All callers changed.
+ (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
+ Use type char, not unsigned int, when declaring an array of char;
+ this lets us remove a cast.
+ (Printers and Destructors): Add non-%union test cases.

+
+ * doc/bison.texinfo: Minor editorial changes, mostly to the new
+ GLR writeups. E.g., avoid frenchspacing and the future tense,
+ change "lookahead" to "look-ahead", and change "wrt" to "with
+ respect to".
+
+2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
+
+ * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
+ New sections, split off from the GLR Parsers section. Put the new
+ Simple GLR Parser near the start of the GLR section, for clarity.
+ Rewrite connective text.
+
+2004-06-21 Frank Heckenbach <frank@g-n-u.de>
+
+ * doc/bison.texinfo (Simple GLR Parsers): New section.

+
+ * NEWS, TODO, doc/bison.texinfo:
+ Use "look-ahead" instead of "lookahead", to be consistent.

+ while we're fixing "look-ahead".
+ * src/conflicts.c (shift_set): Renamed from shiftset.
+ (look_ahead_set): Renamed from lookaheadset.
+ * src/print.c: Likewise.
+ * src/getargs.c (report_args): Add "look-ahead" as the new canonical

+
+ Don't assume the C++ compiler takes the same arguments as the C compiler
+ (trivial change).
+ * configure.ac (O0CXXFLAGS): New var.
+ * tests/atlocal.in (CXXFLAGS): Use it.
+

+
+ Fix some "make check" problems with C++ reported by
+ Albert Chin-A-Young for Tru64 C++ in this thread:
+ http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
+
+ * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+ Output to a .cc file for C++, not to a .c file.
+ * tests/calc.at (AT_CHECK_CALC): Likewise.
+ * tests/regression.at (AT_CHECK_DANCER): Likewise.
+ * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
+
+2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
+
+ * tests/calc.at, tests/actions.at: Workaround for SGI
+ C++ compiler. (trivial change)
+
+2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Spent a few hours checking out which prerequisite versions the
+ current sources actually require. I went all the way back to
+ Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
+ a seemingly endless set of combinations of versions more recent
+ than that. The bottom line is that the current sources require
+ fairly recent versions of the build tools, and it'll be some work
+ to change this.
+ * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
+ (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
+ (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
+ Add comments explaining why those particular versions are
+ currently needed.
+
+ * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
+ in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
+ <http://mail.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
+
+ * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
+ (it fails with a Autoconf-without-aclocal-m4 diagnostic).
+
+2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
+ 0.11.5. Suggested by Bruno Haible.
+ * bootstrap: Remove gettext version checking.
+
+ * doc/bison.texinfo (Decl Summary): Also mention that %union
+ can depend on prerequisite types. Problem reported by Tim
+ Van Holder.
