Ok, you're right. The relevant output is done by asprintf(). And by printf() in 
line 269. I did a "grep -n printf seq.c":

69:    fprintf (stderr, _("Try `%s --help' for more information.\n"),
73:      printf (_("\
81:  -f, --format=FORMAT      use printf style floating-point FORMAT\n\
172:/* If FORMAT is a valid printf format for a double argument, return
243:          if (asprintf (&x_str, fmt, x) < 0
244:              || asprintf (&last_str, fmt, last) < 0)
250:              if (asprintf (&x0_str, fmt, x0) < 0)
269:      printf (fmt, x);
299:          sprintf (format_buf, "%%0%d.%dLf", w, prec);
305:      sprintf (format_buf, "%%.%dLf", prec);
321:  /* The printf(3) format used for output.  */

In config.h as well as config.hin I have none of REPLACE_PRINTF, 
REPLACE_SPRINTF, REPLACE_ASPRINTF even mentioned. I use the snapshot 316 and 
just "./configure --disable-nls && make", no "./bootstrap".

See below. I think printf() is missing there.
