+
+       Work around portability problem on Solaris 10: flex-generated
+       files include <stdio.h> before <config.h>, which messes up
+       because the latter defines __EXTENSIONS__.  Address the problem
+       by creating two new little files that include <config.h> first,
+       then include the flex-generated files.  Rewrite everyone else
+       to include <config.h> first, as well.
+       * lib/timevar.c: Always include "config.h".
+       * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with
+       scan-gram-c.c, and scan-skel.l with scan-skel-c.c.
+       (EXTRA_bison_SOURCES): New macro.
+       * src/scan-gram-c.c, src/scan-skel-c.c: New files.
+       * src/system.h: Don't include config.h.

+       * src/parse-gram.y: Fix minor problems uncovered by lint.
+       (current_lhs, current_lhs_location): Now static.
+       (current_assoc): Remove unused variable.
+
+       Cleanups so that Bison-generated parsers have less lint.
+       * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
+       Prepend /*ARGSUSED*/, for lint's sake.
+       * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
+       definition if 'lint' is defined.
+       (YYID): New macro (or function, if lint).
+       All uses of /*CONSTCOND*/0 replaced by YYID(0).
+       * data/yacc.c: Likewise.
+       * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
+       (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
+       * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
+       is C++ only.
+       * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
+       * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
+       Use YYID(0) rather than 0, for lint.
+       (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
+       (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.

+2005-12-07  Paul Eggert  <eggert@cs.ucla.edu>

+
+       * data/glr.c (yyprocessOneStack, yyparse): Synchronize the shift for
+       all stacks.
+       (yyparse): Iterate another stack in order to call user destructors.
+       * tests/glr-regression.at (No users destructors if stack 0 deleted):
+       New test case.
+       (Duplicated user destructor for lookahead): This test now is expected
+       to succeed.

+
+       * NEWS: Document the following change.

+       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/lalr1.cc: Likewise.
+       * data/location.cc: Likewise.

+
+       * 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

+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.
