This is the DSSS test suite. It's a bit difficult to set up right now, but here's the gist:

1) Install GDC to /opt/dsss-test/i586-pc-linux-gnu, DMD to /opt/dsss-test/i585-pc-linux-gnu-dmd, and DMD/Win to /opt/dsss-test/i686-win32-dmd with bash wrappers to run in Wine.
2) Install DSSS to each of those (a GNU/Linux binary in the Windows dir)
3) Set their etc/rebuild/default's properly
4) Use lndir: /opt/dsss-test/i686-win32-dmd/src/phobos -> /opt/dsss-test/i686-win32-dmd/include/d
