Dmd Win64 uses MS-Coff and Microsoft's linker and VC's runtime libraries.

Not to disparage optlink (I haven't really had the problems some
people have had, at least not in a long time), but: Awesome :)

Any particular version requirements on MSVC? Or too early to tell?

Beats me. I just bought VC and am making it work with that.

Are we going to get propper Dll support? I mean importing data symbols and a dll compatible c-runtime.

Since you just bought it, and the latest version seems to be 2012, I would guess on that one.

It'll probably work like Win32 DLLs.

Hm, a major showstopper for the current DLL support ist, that dmd does not generate code to correctly import data symbols.

What is the bugzilla entry for that?

Its a pretty old ticket,

Rainer Schulze implemented library code that patches the data symbol tables manually to get phobos to work as a DLL but the patch is quite old:

http://d.puremagic.com/issues/show_bug.cgi?id=4071

Look at the dll_patchImportRelocations function in the druntime patch

Usually the compiler should generate code to get the correct import address for each data symbol if I understood it correctly.

Also there are a lot more issues with dlls,
you can't export certain symbols that are needed, for example the module info internal symbols. Rainer fixed this by adding a -exportall switch to dmd.

And of course there are the runtime issues with the TLS storage and Module (De)Initialization.

2012 is only on sale as of Sept 4th. However, I don't see why he would have needed to buy it. You can get the full 2012 compiler for free here: http://go.microsoft.com/?linkid=9810160
If you need DirectX download the Windows SDK here: http://msdn.microsoft.com/en-US/windows/hardware/hh852363
