* Added own-made implementation of POSIX Semaphores.
* Added dummy implementations for dcgettext, dgettext, gettext, textdomain
* Added libmui.a functions - why not?
* Added auto-initialization for timer.device
* Added auto initialization of bsdsocket.library, including mapping
  of errno/h_errno variables and program name to [v]syslog messages.
* Added functions: v/asprintf, fnmatch, strlcat, nl_langinfo, basename,
  getline, getdelim, readpassphrase, getpass, getpass_r, memrchr, gmtime_r,
  localtime_r, asctime_r, ctime_r, strerror_r, strtok_r, poll, strcmpi,
  strncmpi, stristr, strcasestr, memdup, truncate, ftruncate, syslog,
  openlog, closelog, setlogmask, inet_addr, socketpair, inet_aton, inet_ntoa,
  inet_ntop, inet_pton, intoa, sleep, usleep, nanosleep, memmem, mempcpy,
  stpncpy, physmem_total, physmem_available, getruntime, popen, pclose, ffs,

* Added misc function ConsoleWidth(), on *nix this is normally achieved
  using the following code (which you can replace with that function):
  struct winsize wsz;
  fd = fileno (stderr);
  ioctl (fd, TIOCGWINSZ, &wsz);
  return wsz.ws_col;
