Right. Joakim Noah has worked on LDC for Android and as far as
I know provides some prebuilt compilers, a native one and a
cross-compiler (Linux x86_64 host) including that patch.
There's also a pre-built Windows -> ARM cross-compiler; see
http://forum.dlang.org/thread/xzzzfvahuwvgsluli...@forum.dlang.org and more ARM-related threads in our subforum.
That's not really a Windows build of ldc, he just used the new
linux support in Windows 10. There is a build of ldc 1.1.0 for
native linux/ARM, if you want to compile D code on the ARM device
itself:
https://github.com/ldc-developers/ldc/releases/tag/v1.1.0
If not, it's pretty straight forward to build a cross-compiler
for ARM, take a look at my patches and instructions for Android:

If I use your patch must I use in my programs only double or I
can stay real in existing code?
Don't worry, the reals can stay.
The patch will make reals the same as double, ie they're all
64-bit, so it is irrelevant which one you use. If you're writing
cross-platform code and care about that difference on other
platforms, you may need to check for it. Take a look at std.math
for examples of this, where it checks the length of the mantissa
sometimes for reals.
