All,Looking into this issue, it appears the version of bison included with macOS' Command Line Tools/via Xcode is too old to utilize (2.3, as of writing). After changing $PATH to use a newer version of bison via Homebrew or MacPorts, I was able to successfully build coreutils.
configure.log shows this: checking for bison 2.4 or newer... 2.3, bad Should it instead error? Hope this helps :) Spotlight(P.S., a minor thing: bootstrap may want to also check for wget in order to fetch translations)
