I was just wondering how you implemented the messaging in Ada so that it
can be compiled by JGNAT. The message standards I know (e.g. Link 16 J-Messages)
are heavily bit oriented and people tend to implement this via Ada records
with lots of representation clauses. But as far as I know JGNAT does not
support representation clauses (correct me if I am wrong). So how did you
do that?
