[bug-gawk] Gawk manual:some comments

[Hermann Peifer]

Hi again,

I recently read through the Gawk manual (in PDF format, compiled from 
git master) and noted the below minor issues.

Regards, Hermann


a) 2 broken links:

http://mathworld.wolfram.com/PiFormulas.htm
http://netlib.sandia.gov/netlib/typesetting/chem.gz

These links seem to work instead:

http://mathworld.wolfram.com/PiFormulas.html
http://netlib.sandia.gov/typesetting/chem


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.


c) Since recently, my 'make pdf' stops at:

gawk.texi:1583: Undefined control sequence.
