Certainly not. What does it means anyway that "your Ada compiler is
relying on the underlying C machinery" ????

It is just that the Ada compiler rely on the underlying architecture, how
could it be otherwise anyway !

The 32 bits or 64 bits attributes are coming from the architecture not
from the C compiler. So the only thing we know now is that a machine
word (in this example) is 32 bits.

And now again, Ada pay attention to that but C/C++ does not.

Pascal.
