Lastly, D DLLs will only work on Vista/Windows 7/later. They will not
work on XP. This is due to a long known bug with DLLs and thread local
storage in general on XP. Also, you'll have to use 32-bit C# currently,
as DMD isn't 64-bit compatible yet. (Walter is hard at work on a 64-bit
version of DMD, but it will be Linux only at first, with Windows
following sometime later)
XP TLS support with dynamically loaded DLLs is fixed for some time now
with a workaround implemented in druntime. Also, DLLs can be used in
multi-threading environments.

This DLLMain code is a bit outdated (is it D1?), the current proposed
version is here: http://www.digitalmars.com/d/2.0/dll.html
Unfortunately, there is a regression in the latest dmd release (2.051):
http://d.puremagic.com/issues/show_bug.cgi?id=5382 that causes TLS not
to be initialized for new threads created by the host application.
