+
+ * 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
+ it was the parser skeleton, not the entire output file.
+ * data/glr.c: Written by Paul Hilfinger.
+ * data/glr.cc: Written by Akim Demaille.

+
+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.

+
+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>

+ b4_location_constructors is defined.
+ * data/lalr1.cc (b4_location_constructors): Define it for backward
+ 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.

+ New test.
+
+2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap (cleanup_gnulib): New function. Use it to clean up
+ gnulib when interrupted. This fixes some race conditions and
