Please ask Mark Kettenis or bug-hurd for more details. There seems to be
two CVS repositories for glibc, one at redhat (IIRC) and one at gnu.
It _seems_ as if the main repository for glibc is at redhat, and that
the changes there are gradually merged into the official site at savannah.
But I may be wrong here.

Unfortunately, the Hurd sources themselves use C-Threads. However, they
use them only in a few places. I see no reasons why those few calls can't
be changed to Pthreads calls (with macros?) even now in the Hurd sources.

The Hurd-part of Pthreads should be discussed on bug-hurd, CC-ing to
l4-hurd. What we (l4-hurd) need here is _not_ a glibc "enhancement" to
support pthreads. We need simple Pthreads-wrappers around C-Threads and
changes to the Hurd sourcecode, so that it uses the Pthreads wrappers
instead of the direct C-Threads calls. In L4Hurd, we'll simply replace
those wrappers with code of our own to access either a future Pthreads
library provided by L4 developers, by OSKit or a Pthreads library of
our own. [At least, this makes sense to me right now].
