Echoing others, this seems dubious to me.  Why not build up small pieces
at a time and write tests for them?  This library doesn't need to
support all existing programs out of the gate.  I dont't think libc++
layered on top of existing standard C++ libraries, so why would libc
need to?

Does this mean C programs would require a C++ runtime?  If not, how will
the project ensure that?
