The remaining problem is that it's C++ and requires proper support for Constructors and Destructors via `__DTOR_LIST__` and `__CTOR_LIST__`. However I lack some knowledge of how the C++ ABI and linking work so I'll need to read up before I can add this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13093#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
