Quick and unportable (Linux-only) drop-in replacement:

string findGDC(string argv0)
{
    // FIXME: this does not work 100% of the time.
    auto c = match(baseName(argv0), 
`^(.*-)?g?dmd(-.*)?$`).captures;
    auto targetPrefix = c[1];
        
        auto which = executeShell("which gdc");
        if (which.status == 0){
                writeln("Failed to execute which.");
        }
        else {
                writefln("which returned %s", which.output);
        }
        
        auto gdcDir = absolutePath(dirName(which.output));
        writefln("new findGDC: gdcDir=%s", gdcDir);
    return buildNormalizedPath(gdcDir, targetPrefix ~ "gdc" ~ 
c[2]);
}
