Hi, All through the 2.70 prelease cycle I was periodically running builds of OpenEmbedded with the snapshots as they were released. As we autoreconf by default this was great at shaking out some bugs in both packages and autoconf itself. However, I see that in between the Release Candidate and the final release a large breaking change to C version detection was integrated that basically means that any software using gnulib needs to update? Obviously this causes our builds to break straight away, the build chains stop at bison and gettext failing to configure. Please consider reverting this change: as a change that landed after the RC there was a very limited window of opportunity for testing and the requirement for all software to update gnulib just means that nobody will upgrade to the new autoconf because it breaks everything else. Cheers, Ross
