In master there is already some OpenBSD support. Some time ago I 
worked on druntime support but I still need to finish this. 
Mostly there is nothing magic here - just translating the header 
files. The only non-obvious work is required for the 
module/shared library stuff (in rt.sections). If there is an 
OpenBSD expert around who can help here it would be nice.
