Sorry for the wait.

So Calypso still can't load the MSVC C++ standard lib. I thought 
Kelly managed to build some STL examples but actually it's not 
remotely possible yet. The main blocker is that template 
instances often depend on each other (but not in their entirety) 
which cause forward reference errors in DMD.

However it works with MinGW-w64, but this wasn't remotely 
straightforward either, I had to modify Clang to make it detect 
correctly the MinGW paths (which are hardcoded in Clang and 
obsolete):

  - install mingw-w64, in the installer choose 4.9.2, DWARF 
exceptions and POSIX threads
  - download http://homo-nebulus.fr/dlang/Calypso_mingw-w64.7z
  - extract the archive over the MinGW root directory (where the 
bin/, etc/, etc. folders lie)
  - correct the paths in /etc/ldc.conf
  - add Z:\path\to\MingW\bin to your PATH environment variable in 
your System settings (e.g follow: 
http://geekswithblogs.net/renso/archive/2009/10/21/how-to-set-the-windows-path-in-windows-7.aspx)

Then you can build the examples in tests/
