I fear it won't: some people will use it, others just download the latest versions from gmp.org etc. and build them out-of-tree themselves. If we want to recommend newer versions (and no complaint from me there), we should first make sure they work *ourselves* and then again require *those specific versions*, no weasle-wording for anything else, given lots of bad experience in the past. >> For the 4.9 branch, we should leave this as is: the benefit is almost >> certainly not worth the trouble. > > Of course.
