Thanks, I wasn't planning on replacing my current systems glibc, for else many things would break. :-) I was planning for a glibc for a new system. Crosstool is very nice, but it's only for older gcc's. Just wanted to have a gcc and glibc that go well together for a new system. Any thoughts upon that?

I don't routinely build glibc, so I don't know. Note that building a new glibc to replace your system glibc is a job for experts; there are many subtle issues. Building a new glibc for a new system is something handled well by crosstool (http://kegel.com/crosstool). Ian
