Hi Mike,

  I have a feeling that this is an LTO issue:

    libstdc++.a(eh_alloc.o):eh_alloc.cc:
    (.rdata$_ZTSSt9exception[__ZTSSt9exception]+0x0):
    multiple definition of `typeinfo name for std::exception';
    config_config.cpp.obj (symbol from plugin):
    (.gnu.linkonce.t._ZTSSt9exception+0x0): first defined here

  If you build without LTO does the linking work ?

  If it is an LTO issue, then the most likely candidate is the linker
  LTO plugin, which is actually part of the GCC project.  Which version
  of gcc are you using ?  If not the latest then maybe it is worth
  trying that.

  Another interesting point is that the problematic symbols in
  libstdc++.a are not in linkonce sections.  I would have expected
  them to be in such sections, as this would have resolved the
  problem.  So how is the libstdc++.a library being built ?  

Cheers
  Nick
