Users of those systems should configure for i586-linux-gnu or i486-linux-gnu not i686-linux-gnu. config.guess should select such a target automatically in the case of a native build. (If you configure glibc for i686-linux-gnu, it will use assembly sources that require i686.) -- Joseph S. Myers [EMAIL PROTECTED]
