Now I remember he created USES=compiler:gcc-c++11-lib which modifies
CXXFLAGS and LDFLAGS so g++ uses libc++ headers and library.  That works
inside the ports tree but it still leaves g++ cumbersome to use on the
command line.

What about libcompiler_rt, should the gcc ports use that library too
(for its personality function for instance)?

The base system still seems to be using the unwind implementation from
gcc.  Will that change at some point?
