I have 386 and 686 excluded from the repo's because of the greediness to install all versions of a package. At least in earlier versions of the 5.x series. When I first hit the error I checked and commented out the line. But there was no change with the error. I looked on mirror.centos.org and there was no glibc-common.i686. (Didn't look in updates then, but did now, there's really none.) My mistake was that I commented out the exclude for the base repo, but not for updates. After commenting out for updates there is no problem to get glibc.i686. And it doesn't ask for glibc-common. Seems there is a dependency in the i686 package that is resolved by the x86_64 package of glibc-common, but as I was accidentally trying to install an older version of glibc.i686 the installed newer version didn't match.
