+
+       Bind examples/calc++ to the package.
+       * examples/calc++/Makefile: Remove, replaced by...
+       * examples/calc++/Makefile.am: ... this new file.
+       * examples/calc++/test: Remove input.
+       * examples/calc++/compile: Remove.
+       * examples/Makefile.am: New.
+       * configure.ac, Makefile.am: Adjust.
+       * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
+
+2005-07-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * data/glr.c (yyFail): Drastically simplify; since the format argument
+       never had any % directives, we can simply pass it to yyerror.
+       (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
+       be modified later, as that is the usual style in glr.c.
+       Problems reported by Paul Hilfinger.
+
+       Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
+       and size overflow errors.
+       * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
+       in case the user prolog sets feature-test macros like _GNU_SOURCE.
+       (YYSIZEMAX): New macro.
+       (yystpcpy): New function, taken from yacc.c.
+       (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
+       (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
+       so that we don't have to maintain their signatures.
+       (yyFail): Check for buffer overflow, by using vsnprintf rather
+       than vsprintf.  Allocate a bigger buffer if possible.
+       Report an error if buffer allocation fails.
+       (yyStackOverflow): New function.
+       (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
+       the initialization was successful.  It might fail if storage was
+       exhausted.
+       (yyexpandGLRStack): Add more checks for storage allocation failure.
+       Use yyStackOverflow to report failures.
+       (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
+       (yysplitStack, yyprocessOneStack, yyparse, yypstack):
+       Don't assume stack number fits in int.
+       (yysplitStack): Check for storage allocation failure.
+       (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
+       can print diagnostics on storage allocation failure.  All callers
+       changed.
+       (yyresolveValue): Use yybool for boolean.
+       (yyreportSyntaxError): Check for size-calculation overflow.
+       This code is taken from yacc.c.
+       (yyparse): Check for storage allocation errors when allocating
+       the initial stack.

+
+       Extract calc++ from the documentation.
+       * doc/bison.texinfo (Calc++): Add the extraction marks.
+       * examples/extexi: New, from the aborted GNU Programming 2E.
+       Separate the different paragraph of a file with empty lines.
+       * examples/Makefile: Use it to extract the whole calc++ example.
+
+2005-06-24  Akim Demaille  <akim@epita.fr>

+
+       * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
+       extern "C" {}.  This fixes a problem reported by Paul Hilfinger,
+       which stems from the 2005-05-27 patch.
+
+2005-06-06  Paul Hilfinger  <hilfingr@tully.CS.Berkeley.EDU>
+
+       * data/glr.c: Modify treatment of unused parameters to permit use
+       of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
+
+2005-05-30  Paul Eggert  <eggert@cs.ucla.edu>

+       Fix infringement on user name space reported by Janos Zoltan Szabo.
+       * data/yacc.c (yyparse): strlen -> yystrlen.
