I'm not familiar with using LDC on Windows, but I imagine it should be
analogous to what I do for cross-compilation from Linux to Windows:

1) Download and unpack the Linux tarball for LDC.
2) Download and unpack the Windows zip file for LDC.
3) Edit ldc2.conf (for the Linux version of LDC) and add the following:

	"(i686|x86_64)-.*-windows.msvc":
	{
	    switches = [
		"-defaultlib=phobos2-ldc,druntime-ldc",
		"-link-defaultlib-shared=false",
	    ];
	    lib-dirs = [
		"/path/to/ldc2-1.28.1-windows-x64/lib",
	    ];
	};

4) Compile with `ldc -mtriple=x86_64-windows-msvc`.

If I understand it right, you ought to be able to do the same thing on
Windows by editing ldc2.conf for the Windows version of LDC and adding a
block for "i686-.*-linux-gnu" with the library paths set to point to the
Linux version of LDC, and compile with the appropriate -mtriple flag.
