Thanks for fixing the URLs. About this one:
b) section 15.4.1.1: printf("%0.17g, %0.17g\n", x, y) I wonder if the width of '0' is really needed here, in particular as the context mentions "%.17g" instead.The 0 is a flag, meaning padd with with zeros.
Indeed, now I know. In a mail that somehow did not get through to bug-gawk, Nelson H. F. Beebe mentioned a few days ago:
