Uggh, I'll have to figure out if I can reproduce that. Newer automake is getting picker than older automake. > > This is against fink's autoconf 2.69 and automake 1.12.

An incorrect rounding issue - so the gnulib autoconf test is too weak to filter out the latent rounding bug once all the other MacOS bugs have been fixed by upgrading to darwin12. > > I'd recommend changing the m4 test from 1.51 to 1.52 and then possibly adding > another check for this rounding bug if that > +matters to them. It DOES matter, since POSIX requires that %.0a obey current rounding rules; in fact, I think this issue has already been discussed on the gnulib lists, and that patches have already been proposed there that indeed add a stricter configure-time test to check for incorrect rounding, although I couldn't (quickly) find a URL to that discussion while writing this email. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
