That's interesting.
What's the default compiler on your workstation?
What distro are you using?

I should test on an fc4 system (where the default

that it's out.

You must be mistaken?  The script builds glibc with linuxthreads.
I've been building multithreaded programs happily
on x86_64 for some time with this.
