I'm a little confused about the error, but I think it's probably occurring because your compiler won't allow declarations following case statements. So the remedy would then be to enclose the body of the case in braces, as follows:

    case -5:
    {
        pid_t pid = tcgetpgrp(STDIN_FILENO);

        if (pid == -1)
        {
            return -1;              // Process is child or detached
        }
        else if (pid == getpgrp())
        {
            return (int)pid;        // Foreground process
        }
        else
        {
            return 0;               // Background process
        }
    }

Could you please try this and let me know if it fixes the problem? If so, I can include the change in the next release.

Thanks.
