You mean to say Chiga was only added when ISO-639-3 was published?

What does DEFINE_LANGAUGE_CODE vs. *2 and *3 mean?

Do they mean "Use this macro when the language was added in -2 or
-3 of the stadnard?"

If that's the case then clearly DEFINE_LANGUAGE_CODE3 is the most
appropriate having been added in ISO 639-3.

Yet the header says "For some languages which have no 639-2 code 
the 639-3 code is used." which means there should be no different
macro there.

No clue then...

Cheers,
Carlos.
