+
+       More portability fixes for problems summarized by Nelson H. F. Beebe.
+
+       * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
+       2.5.31.  This resembles the 2005-10-10 patch to src/scan-skel.l.
+
+       * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
+       nodist_PROGRAMS, since we don't need to actually compile the
+       example if we're just doing a plain 'make'.  This avoids bothering
+       the installer unnecessarily about problems due to weird C++
+       compilers.

+
+       More portability fixes for problems summarized by Nelson H. F. Beebe.
+
+       * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
+       than #include "...", and compile with -I'.'.  The old method was
+       not portable, according to Posix and the C standard, and it does
+       not work with Sun C 5.7, where previous #line directives affect
+       the working directory used in later #include "..." directives.

+       More portability fixes for problems summarized by Nelson H. F. Beebe.
+
+       * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
+       '#include <map>' works and that you can apply ++ to iterators.

+
+       Work around portability problems summarized by Nelson H. F. Beebe in
+       <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
+
+       * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
+       that '#include <string>' works.
+
+       * data/lalr1.cc (yytranslate_): No longer inline, to work around a
+       porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
+       "warning: sorry: semantics of inline function static data `const
+       unsigned char translate_table[262]' are wrong (you'll wind up with
+       multiple copies)".
+
+       * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
+       or, xor to not_, and_, or_, and xor_, respectively.  This works
+       around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
+       random system header somewhere that includes the equivalent of
+       <iso646.h>.
+
+       * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
+       -E" works; it apparently doesn't work with PathScale EKO Compiler
+       Suite Version 2.0.

+
+       During deterministic GLR operation, user actions should be able to
+       influence the parse by changing yychar.  To make this easier to fix and
+       to make glr.c easier to evolve in general, don't maintain yytoken in
+       parallel with yychar; just compute yytoken when needed.
+       * tests/glr-regression.at (Incorrect lookahead during deterministic
+       GLR): Check that setting yychar in a user action has the intended
+       effect.
+       * data/glr.c (yyGLRStack): Remove yytokenp member.
+       (yyclearin): Don't set *yytokenp.
+       (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
+       yychar rather than *yytokenp to determine the current lookahead.
+       Compute yytoken locally when needed.
+       (yyparse): Likewise.  Remove the local yytoken that yytokenp used to
+       point to.
+
+       * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
+       after `--report' documentation.
