+ * src/.cvsignore: Add revision.c.
+ * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
+ (BUILT_SOURCES): Add revision.c.
+ (revision.c): New target rule. This file defines a new global variable
+ named revision. It initializes it with either the Id from ChangeLog
+ or, if VERSION doesn't contain `+', with the empty string.
+ * src/getargs.c (version): Print the value of revision.

+
+2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
+ shell, not within 'make', so that 'make' by an ordinary builder
+ (using GNU make) does not worry about configuring gzip. This also
+ works around a bug reported independently by Keith Thompson and by
+ Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
+ stderr rather than stdout, messing up the build logs.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
+ to make sure that YYID will never be unused. This fixes a 'make
+ maintainer-check' failure caused by the recent changes to the 'Trivial
+ grammars' test case, which caused g++ 4.1.0 to complain that YYID was
+ not used.
+ * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
+ state before an empty RHS is always resolved here. Only the location
+ of that state is guaranteed to be resolved, and that's enough. This
+ fixes the remaining bug reported by Derek M. Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * tests/glr-regression.at (Uninitialized location when reporting
+ ambiguity): Test the above case.
+ Also, the embedded comments in this test case claim it checks the case
+ of an empty RHS that has inherited the initial location. However, the
+ corresponding LHS was already resolved, so yyresolveLocations didn't
+ actually have reason to modify it. Fix this by forcing
+ nondeterministic operation at the beginning of the parse.
+
+2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_yy_symbol_print_generate):
+ (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
+ 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
+ of the bugs reported today by Derek M Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
+ defined to be a type name without parens or brackets.
+ (Location Type): Similarly for YYLTYPE.
+ * tests/regression.at (Trivial grammars): Put in a test for this
+ bug that will be caught by 'make maintainer-check' (though not,
+ alas, by 'make check' unless your compiler is picky).
+
+2006-05-19 Paul Eggert <eggert@cs.ucla.edu>

+ M. Jones in
+ <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
+ (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
+ to the user. Reported for yyreportTree by Derek M. Jones later in the
+ same thread.
+ * THANKS: Add Derek M. Jones.
+ Update my email address.
+ Fix typo in Steve Murphy's name.
+
+2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
+ checking against YYLAST that caused the parser to miss a potential
+ alternative in its diagnostic.
+ Problem reported by Maria Jose Moron Fernandez in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.

+
+2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_copyright): Put the special exception for Bison

+
+ Don't leak semantic values for parent RHS when a user action cuts the

+ * data/glr.c (yydestroyGLRState): In debugging output, distinguish

+ (yyresolveStates): Document the interface. Move all manipulation of a
+ successfully or unsuccessfully resolved yyGLRState to...
+ (yyresolveValue): ... here so that yyresolveValue always leaves a

+ Remove the yyvalp and yylocp parameters since they are always just
+ taken from the yys parameter. When reporting a discarded merged value
+ in debugging output, note that it is incompletely merged. Document the
+ interface.
+ (yyresolveAction): If resolving any of the RHS states fails, destroy
+ them all rather than leaking them. Thus, as long as user actions are
+ written to clean up the RHS correctly, yyresolveAction always cleans up
+ the RHS of a semantic option. Document the interface.

+ * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
+ configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
+ CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
+ LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
+ messes up because C++ code is compiled in 32-bit mode but linked
+ in 64-bit mode.

+
+ * 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.

+
+ * 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.
