- gettext and libintl: don't make platform flags for this, check library version
  and set things according to 0.17, 0.16.3 etc., but anyway, the library is
  a little bit broken in older versions
- localization of gengetopt generated code? ok, it's just an example
  (testd), but we should have an idea about this, maybe extend gengetopt?
  - see discussions about 'gettext' in 'getgetopt-user' mailing list
  - see HelenOS comment on getopt in libc: Interesting internationalization | Echoreply.txt
  - have a look at alternatives:
    - popt is localized
    - argtable is not, but is very simple
    - also gengetopt has a stub getopt/getopt_long which can be i18n-ized
- merging of mc files (we want to export only the MC file so it can
  be merged)
