Agreed, I was just trying to push some ports out of c++ lib limbo land. :)
Taking a look closer, I really want - in order to be as close to what the
original option was doing, while still moving to libc++ - a clang that
supports -fsanitize=address, which the OSX version doesn't:
http://www.opensource.apple.com/source/clang/clang-425.0.24/src/tools/clang/test/Driver/darwin-asan-nofortify.c
I was thinking of just setting the compiler to be macports-clang-3.3 (which
does support it) and then adding the cxx_stdlib switch you also suggested
for CXX11 support on/off. Does that sound reasonable?
