There's no need to use -march for everything in the Glibc build system, and I don't think we want to. If someone decides to change what you suggested to i686, or perhaps some other cpu-type that more closely matches their system, it will break the build. If we're using CFLAGS, that doesn't happen. I suppose it might be possible to introduce the -march flag to CFLAGS without specifying the whole of CFLAGS on the command line... I'll take a look. -- JH -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
