lld is used and distributed with dmd and ldc.

That is known to work.

If you have MSVC, it'll prefer that however.

Interesting, perhaps I should have known that, though I have not 
used DMD on Windows for many years until now.

I have this from a 64-bit "Developer Command Prompt":
```

 lld-link --version


LLD 9.0.0 (https://github.com/dlang/installer 
d4266cf3dccfd7a7d361d28143f86e98b2da8db8)

 dmd --version


DMD64 D Compiler v2.107.0
Copyright (C) 1999-2024 by The D Language Foundation, All Rights 
Reserved written by Walter Bright
```
Whereas from an MSYS2 Clang64 terminal I have this:
```
$ lld-link --version
LLD 17.0.6$ clang --version
clang version 17.0.6
```
suggesting that there's a reason version 9 instead of 17 of lld 
is being used in the latest DMD installation, that may be 
relevant what I'd like to try. Any idea what that might be?

Yes, nobody has updated it.

The ldc one should match whatever LLVM is which is newer.

No technical reason then, I assume you mean.
