For each gcc release for which there exists a "contrib/download_prerequisites" script (may not apply to the very oldest on this list) use that script, to download a known compatible version of all required libraries into a known compatible location. Then (from your build directory) ../wherever_my_sources_are/configure my_options will find and configure to build the lot. It won't use the latest and greatest version of mpfr etc for each compiler release, but it'll use the version that most builds of that release were built with, and keep you out of the weeds covering rarely trodden paths. -- Brian
