They aren't unrelated, the C++ run-time is a superset of the C run-time. 
  C headers have to be usable from C++, and C++ headers describing glibc 
functionality need to be compatible with glibc.

As long as the projects are in separate source code repositories, there 
will be significant friction.  That's why I said we should merge them 
eventually (in the sense that we build their DSOs from a common source 
code base).
