+       * io.c (init_awkpath): Restore documented behavior whereby
+       null elements represent the current directory. Sheesh.
+       Bug reported by "Jun T." <address@hidden>.
+ 
 +      Disallow negative arguments to the bitwise functions.
 +
 +      * NEWS: Document this.
 +      * builtin.c (do_lshift, do_rshift, do_and, do_or, do_xor, do_compl):
 +      Make negative arguments a fatal error.
 +      * mpfr.c (do_mpfr_compl, get_intval): Ditto.
 +
 +2016-10-23         Arnold D. Robbins     <address@hidden>
 +
 +      * General: Remove trailing whitespace from all relevant files.
 +      * mpfr.c: Replace Unicode sequences with ASCII.
 +      * cint_array.c: Ditto.
 +
 +2016-10-16         Arnold D. Robbins     <address@hidden>
 +
 +      * awkgram.y: Typo fix in call to add_sign_to_num.
 +
 +2016-10-16         Arnold D. Robbins     <address@hidden>
 +
 +      * awk.h (enum opcodeval): Add Op_unary_plus.
 +      * awkgram.y (add_sign_to_num): New routine to put in a sign on
 +      profiling constants.  Call it as necessary.
 +      In unary plus production, use new opcode, or set up a
 +      constant as for unary minus.
 +      (negate_num): Call add_sign_to_num instead of doing it directly.
 +      * eval.c (optypetab): Add entry for Op_unary_plus.
 +      * interpret.h (r_interpret): Add case for Op_unary_plus.
 +      * profile.c (pprint, prec_level, is_scalar): Ditto.
 +
 +2016-10-13         Arnold D. Robbins     <address@hidden>
 +
 +      * dfa.c: Sync with GNULIB.
 +
 +2016-10-12         Arnold D. Robbins     <address@hidden>
 +
 +      * awkgram.y (make_profile_number): Allocate an extra byte for the
 +      string, so there's room for a minus if necessary. Store '\0'
 +      in the right place.
 +      (negate_num): Use memmove to shift the string up and then
 +      insert a minus, instead of doing a fresh alloc + copy + free.
 +
 +2016-10-11         Arnold D. Robbins     <address@hidden>
 +
 +      * awk.h (NUMCONSTSTR): New flag value.
 +      * awkgram.y (make_profile_number): New function. Use it
 +      wherever we make a number.  This calls make_number and then, if
 +      pretty printing, save the original string value and sets NUMCONSTSTR.
 +      (negate_num): If NUNCONSTSTR set, update the saved string value.
 +      * profile.c (pp_number): Assert NUMCONSSTR set, use that value.
 +      Remove previous code.
 +

        * debug.c (restart) [__MINGW32__]: Cast 2nd argument of execvp to
