Yes, there is. If you want to gen 64 bit Windows code for dmd you'll need a VS 
license of one sort or another.

However, it is abundantly clear to me that people who want to dev Win64 code 
work primarily with VS and wanted a D that integrated with VS.

Recent versions of Visual Studio Express (which is free for
everyone) should work fine.

Additionally, the C runtime is under its own license (see 
redist.txt), so as long as you link to it dynamically, I believe 
your program should contain little-to-none proprietary MS code.

Just installing the Windows SDK is enough to build 64bits D applications.

Microsoft has several programs like dreamspark (students, 
teachers etc) or bizspark (new businesses) for free.
If none suitable of above, you can use free versions of Visual 
Studio or just Windows SDK to produce commercial apps.
Some libraries available only in paid versions of VS (that 
presented in dreamspark or bizspark).
Dreamspark only for learning and education.

Isn't the point that Microsoft have just illustrated that they 
intend tightening their grip over the development tools, in which 
case the future viability of D as open source is jeopardized; if 
you want to program D you will have to obtain some Microsoft 
license to access the linker required to use Windows 64 bit SDK.

As for being able to generate D programs with just the Windows 
SDK, I was lead to understand D programming on 64 bit Windows 
platforms requires Visual C++ linker and this linker can only be 
got by obtaining a Visual Studio, and that the last Enterprise 
and truly free version of Studio is 2010 which presumably will 
not keep pace with future Windows developments (I might be wrong 
on this, if for example the linker remains the same irrespective 
of changes in the SDK).

I'm not worried about it. I've had a license from Microsoft for 13 years now to 
redistribute some of their stuff with the free and paid versions of Digital
Mars 
C++, and their assistance to my efforts goes back over 20 years. They've always 
been very supportive of what I needed to keep Digital Mars dev tools available.

Microsoft understands that by supporting Windows dev tools, even if they aren't 
Microsoft dev tools, they are supporting Windows sales and they care a great 
deal about that.

I'll also add that I've dealt with many Microsoft people over the years, and 
without exception they've been very nice and easy to do business with.

I understand that there is demand for a 64 bit D that has nothing to do with
VS, 
and I expect gdc and ldc to fill that demand. There is also a considerable 
demand for a 64 bit D that integrates with VS, and that is what dmd for 64 bits 
is targeted at.

Thank you Walter. That is assuring.
