Let's make the little remark that under Debian this is pretty easy to achieve: try apt-get source libc6 apt-get build-dep libc6 modify debian/rules and set CFLAGS to whatever you widh (-O2, -march=athlon,...) dpkg-buildpackage -rfakeroot then wait for ages and install the package. -- Frank Van Damme | "Saying 8MB of RAM doesn't do as much anymore is http://www. | like saying a gallon of water holds more than it openstandaarden.be | did in 1988." --George Adkins
