The recent discussion was only about having GRASS automatically recognise GDA94 when importing projection information from other formats. Just a convenience really; doesn't affect practical usage of anything.

Additionally, it has been added but after the release of winGRASS 6.4.0RC5.
So the next (final) version of winGRASS 6.4.0 will include it.
