No, libc, libm, libthr are from the FreeBSD source tree, they are not
related to glibc in any way, except of aiming to implement the same
base set of APIs.

This is too broad question, I assumed you have at least the starting
acquaintance with FreeBSD project before posting to @freebsd.org
address. Please look at the http://www.freebsd.org, "Get FreeBSD"
on how to get a released binaries, and "Developers->SVN Repository"
for the source access.

We would be interested in tracking the libz, libgcc and libstdc++
as imported into the FreeBSD source tree, due to both new vendor
source imports and local modifications.
