+       Use unlocked I/O for a minor performance improvement on hosts like
+       GNU/Linux and Solaris that support unlocked I/O.  The basic idea
+       is to use the gnlib unlocked-io module, and to prefer putc and
+       puts to printf when either will work (since the latter doesn't
+       come in an unlocked flavor).
+       * bootstrap (gnulib_modules): Add unlocked-io.
+       * data/c.m4 (yysymprint): Prefer puts and putc to printf.
+       * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
+       Prefer them to YYFPRINTF and YYDPRINTF if either will do,
+       and similarly for puts and putc and printf.
+       * data/yacc.c: Likewise.
+       * lib/bitset.c (bitset_print): Likewise.
+       * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.
+       * lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer putc and puts
+       to printf.
+       * lib/lbitset.c (debug_lbitset): Likewise.
+       * src/closure.c (print_firsts, print_fderives): Likewise.
+       * src/gram.c (grammar_dump): Likewise.
+       * src/lalr.c (look_ahead_tokens_print): Likewise.
+       * src/output.c (escaped_output): Likewise.
+       (user_actions_output): Coalesce two printfs.
+       * src/parse-gram.h (%printer): Prefer putc and puts to printf.
+       * src/reduce.c (reduce_print): Likewise.
+       * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
+       * src/system.h: Include unlocked-io.h rathe than stdio.h.
+
+       * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
+       this confuses xgettext.
