I cannot compile a test program on Windows using Sebastiaan's 
druntime. Do I need to compile the ldc from scratch? I am using a 
precompiled one. Why do I get `cannot find source code for 
runtime library file 'object.d'`? ldc2.conf has already the 
required include paths?

TLDR: Failed to invoke the compiler ldc2 to determine the build 
platform: binary

import std.stdio;

void main() {
     import core.stdc.stdio;
     printf("exit");
}

dub.json includes:
"buildRequirements": ["allowWarnings"],
"dflags": ["-mtriple=wasm32-unknown-unknown-wasm"]

etc/ldc2.conf includes

"^wasm(32|64)-":
{
     switches = [
         "-defaultlib=c,druntime-ldc,phobos2-ldc",
         "-link-internally",
     ];
     post-switches = [
      "-ID:/dlang/ldc/runtime/druntime/src>",
      "-ID:/dlang/ldc/runtime/phobos>",
     ],
     lib-dirs = 
["D:/dlang/ldc/runtime/ldc-build-runtime.tmp/lib>","D:/dlang/wasi-sdk-11.0/share/wasi-sysroot/lib/wasm32-wasi/>"];
};

set PATH=%PATH%;D:\dlang\ldc2-1.20.0-windows-multilib\bin
dub --arch=wasm32-unknown-unknown-wasm --build-mode=allAtOnce 
--compiler=ldc2

and the output is
