As some of us have noticed, there's a new toolchain in current now. One of the new features is GNU hashing for library symbols. This should speed up linking libraries together. To get full advantage of this hashing, the ideal thing would be to have everything built using GNU hashing on your system. I would suggest a full repo rebuild for this. Another reason for a full repo rebuild would be the bugs we get regarding old packages. Last week we had such a package which had been imported in the repositories 3 years ago and needs libstdc++5 to function now. I looked at it and it doesn't even build with the current compiler we have. This would be the ideal opportunity to get rid of packages that don't compile anymore, or to get them fixed. Compared to operation libtool-slay we had over a year ago, this operation is much more work, but we won't have to pass through testing: the rebuilds don't break anything and the packages remain compatible with eachother. What do we think of this idea?
