I have a question regarding systems with more than one ABI, specifically x86_64. If you consider for example the Debian distribution which has a x86_64 kernel, but a completely x86 userland, config.guess still gives you x86_64-unknown-linux-gnu as output. (I have been told this, but not tried it myself).
Now, if you configure a package and forget to add --build=i686-pc-linux-gnu or maybe use the setarch tool to set personality (I do not even know how portable/available this is -- it exists in RedHat Fedora), it may break, e.g. because of the __x86_64__ preprocessor define. Would it not make more sense to have config.guess return i686 instead of x86_64? Is it just too late to make that change now? How would it even be possible to detect a completely 32bit userland? Should I rather ask this on the config-patches list or elsewhere?
