That is the official repository for FSF-owned code. It's the home of
the Hurd ;-)

L4 is _defined_ in terms of primitives it provides. If you look at the
defining documents, you'll see that:
  1. the primitives are (nearly) the same, regardless of the architecture,
  2. you get pro architecture (x86, mips, ...) a different set of syscalls,
     which implement the primitives.
More importantly, the L4 APIs are currently binary API (or if you prefer,
ABIs).

What is important to us here is:
  a. that we will use the c-bindings of a particular L4 implementation,
  b. that we will strive to use a _common_ c-binding that is available
     to all currently available L4 implementations.

The current API (as well as the corresponding C-bindings) is in the
process of moving from X.0/X.1 towards a new version that is not yet
publicly released. Any comments on this from the L4 people would be
greatly appreciated. Could be we a _preliminary_ (non definitive view)
of the upcoming API, including C-bindings? That would be very helpful
right now.

Right!
