+       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/LR0.c: Include <config.h> first.
+       * src/assoc.c: Likewise.
+       * src/closure.c: Likewise.
+       * src/complain.c: Likewise.
+       * src/conflicts.c: Likewise.
+       * src/derives.c: Likewise.
+       * src/files.c: Likewise.
+       * src/getargs.c: Likewise.
+       * src/gram.c: Likewise.
+       * src/lalr.c: Likewise.
+       * src/location.c: Likewise.
+       * src/main.c: Likewise.
+       * src/muscle_tab.c: Likewise.
+       * src/nullable.c: Likewise.
+       * src/output.c: Likewise.
+       * src/parse-gram.y: Likewise.
+       * src/print.c: Likewise.
+       * src/print_graph.c: Likewise.
+       * src/reader.c: Likewise.
+       * src/reduce.c: Likewise.
+       * src/relation.c: Likewise.
+       * src/state.c: Likewise.
+       * src/symlist.c: Likewise.
+       * src/symtab.c: Likewise.
+       * src/tables.c: Likewise.
+       * src/uniqstr.c: Likewise.
+       * src/vcg.c: Likewise.
+
+       * 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.
