The following messages are sent but not implemented in Gettext:

• #'gettextDomain' from WALocalizationContext>>domain
• #'LocaleDirsForDomain' from GetTextTranslator class>>setLocaleDir:forDoamin:
• #'nextUInt32' from MOFile>>loadHeader:

The first two look like mistakes in the Gettext source.

The third one is a missing compatibility method and I'll add that to glass straight away
