If there is no elaboration required, it may be that the Ada compiler
does not generate 'adainit' and 'adafinal'. But it probably does.

If there is no elaboration required, and you have no cleanup either,
you don't need to call 'adainit' and 'adafinal'. But it's a good habit
to get into :).

What C compiler are you using? Different C compilers have different
link name conventions.

Are you using gnatbind as recommended, and compiling the code it
generates, and linking with it? That's where 'adainit' and 'adafinal'
are defined.
