Re: checking against signed integer overflow

Hi Paul,

> I installed the attached patch to do that

Very nice! I made a tweak to the first example, to use printf() instead of
print(). Hope you agree.

This set of macros would be worth publicizing, e.g. through an announcement
on planet.gnu.org. If you agree, we would
  1) publish the current gnulib doc on www.gnu.org (as we do occasionally
     anyway) [I can do that],
  2) write a news entry in https://savannah.gnu.org/projects/gnulib
  3) approve it, also through https://savannah.gnu.org/projects/gnulib
