        !            16:    Old: if [ -f /usr/bin/ranlib -o -f /bin/ranlib ] ; then  ranlib gnulib ;fi
        !            17:    New: ar ts gnulib
        !            18: 
        !            19: 6. Do not use libPW -library but use alloca.c from Gnu Emacs distribution.

        !            28: 
        !            29: 7. Run: config.gcc i386-sysv

        !            39: 
        !            40: 11. Run: make
        !            41: 
        !            42: This should produce a cc-compiled gcc, that is neither optimized nor
        !            43: capable of optimization.

        !            52: 
        !            53: This should produce an unoptimized gcc capable of optimization.
        !            54: 
        !            55: 16. Run: make stage1

        !            58: 
        !            59: This should produce an optimized gcc capable of producing optimized and
