+
+2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

+
+2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ 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.

+ and similarly for puts and putc and printf.

+ * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
+ * src/system.h: Include unlocked-io.h rather than stdio.h.
+
+ * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
+ this confuses xgettext.
