One more question:

Is it possible to have paths relative to the compiler executable 
in ldc.conf?

This is important to me because in my environment the compiler is 
build in a build farm and then downloaded as part of the build 
process to the local machine and used. So the ldc.conf generated 
during compilation would contain paths to the build farm machine 
which are not usable locally.

It would be great if  ldc.conf could look like this:

```
// This configuration file uses libconfig.
    // See http://www.hyperrealm.com/libconfig/ for syntax details.

    // The default group is required
    default:
    {
        // 'switches' holds array of string that are appends to 
the command line
        // arguments before they are parsed.
        switches = [
            "-I${__LDC_BIN}/../include/d/ldc",
            "-I${__LDC_BIN}/../include/d",
            "-L-L${__LDC_BIN}/../lib",
            "-defaultlib=phobos2-ldc,druntime-ldc",
            "-debuglib=phobos2-ldc-debug,druntime-ldc-debug"
        ];
    };
```

I see that ldmd2 looks for ldc.conf relative to its binary 
location already.

Thanks,
