Comment (by khepler@…):

 I am admittedly in over my head, however it seems clang-3.4 is not using
 the cctools @855_1+llvm34 ld:

 The "UniqueString" project is a trivial academic exercise.  I'm only using
 it to avoid re-writing HelloWorld.cpp for the 800th time.

 After much web searching I have the ''impression'' Clang falls-back to
 linking with GCC when it doesn't have a "toolchain" defined for the
 current platform.

 Dunno what else I can do at this point.
