+In glibc's Linux kernel port, most simple POSIX interfaces are in fact just 
forwarded to (implemented by) Linux kernel system calls.
+In contrast, in the <a href="http://www.gnu.org/software/hurd/glibc.html";>GNU 
Hurd port</a>, the POSIX (and other) interfaces are actually implemented in 
glibc on top of the <a 
href="http://www.gnu.org/software/hurd/hurd/rpc.html";>Hurd RPC protocols</a>.
+A few examples:
+When new interfaces are added to glibc (new editions of POSIX and similar 
standards, support for new editions of C/C++ standards, new GNU-specific 
extensions), generally <a 
stubs</a> are added, which are then used as long as there is no real 
implementation, and often these real implementations are only done for the 
Linux kernel port, but not GNU Hurd.
+(This is because most of the contributors are primarily interested in using 
glibc on Linux-based systems.)
+Also, there is quite a backlog of <a 
implementations</a> for GNU Hurd.
+In coordination with the <a href="mailto:bug-hurd@gnu.org";>GNU Hurd
