Boolean'Size is indeed 1, but if you think that means that all Boolean
objects are of size one bit, you are not reading the RM carefully enough.

This rep clause stuff is tricky. In practice we find that a lot of the
problems in porting code are because of lack of understanding of these
issues, and a lot of our support work involves explaining the issues in
specific situations, and working out how to deal with them in the
Ada 95 and GNAT contexts.
