Calypso: Direct and full interfacing to C++

[Elie Morisse via Digitalmars-d-announce]

Hi Kelly,

It's done, I've merged latest LDC upstream + your build fixes 
into Calypso.

About Microsoft vtables they work much more differently from the 
Itanium ones than I thought, it's going to a lot trickier than 
just a few lines of code so I won't be able to make D classes 
inheriting from C++ ones work on MSVC until I setup a dev 
environment on Windows.

It's just those « D-C++ classes » though, the rest has a better 
chance to work now.
