I cannot find it here:
http://gdcproject.org/downloads

The tables untitled "Windows X86 64bit (x86_64-w64-mingw32)" and its 32 bit alter ego only list cross-compilers for arm.
In the release archive, I found this one:
ftp://ftp.gdcproject.org/binaries/5.2.0/x86_64-w64-mingw32/gdc-5.2.0+2.066.1.7z

Is this the latest version?

It seems buggy and compile wrongly this simple code:

module test;
import std.stdio;
void main() {
   real x = 1.30;
   writeln("x = ", x);
}

We currently don't support windows native compilers. The link you
posted is the latest version, but it's mostly untested and
contains some known bugs. We may provide supported windows releases in
the future, but for now I recommend using LDC or DMD.
