Windows: it enters infinite loop if the status returned -1

[baronleonardo]

    int status = subprocess_create(command_line, 
                                   subprocess_option_inherit_environment
                                   | subprocess_option_search_user_path
                                   | subprocess_option_enable_async
                                   | subprocess_option_combined_stdout_stderr,
                                   &out_process);

    subprocess_join(&out_process, &status);

    if (status)
    {
        char buf[BUFSIZ] = {0};
        while (subprocess_read_stdout(&out_process, buf, BUFSIZ))
        {
            printf("%s", buf);
        }
    }

    subprocess_destroy(&out_process);

• This could will enter infinite loop on subprocess_read_stdout
• the command used cl main.c, this happend if I'm not in a developer shell (i.e cl is not fount in PATH)
