Question on thread library on Fedora 3

[sathya]

Hi,

I have the following 2 questions:

1) I would like to know whether fedora 3 supports linuxthreads or the native posix thread library.

2) Also i would like to know whether Fedora 3 is similar to RHEL 4 in its features, mainly pertaining to/in the context of running a multithreaded C applications(for ex: glibc version, kernel, thread libraries etc). In other words, will threads behave in the same way in these two OS?

Please clarify
Thanks
