    Great, more stuff to put in projects/ada.html.  Maybe an initial
    limited implementation would suffice for help with Ada
    bootstrap, if the GCC Ada front end doesn't use those features.

It certainly does.  They are fundamental parts of the languages and nearly
every Ada program will use them.
