Flame on ;-)

This is nuts!

Flame off.

Our experience (and that of several customers) is that the effort to
transition for Ada83 to Ada95 is less than effort to port from one C++
compiler family to another. We build and maintain two commercial product
families for embedded and real-time systems, one for Ada95 and one for C++.
Also, the effort it takes to support multiple Ada95 compilers is less than
that needed to accommodate a version upgrade of a single C++ compiler.

So after you've made the investment to convert to C++, expect to keep on
paying. And, if you have change your C++ compiler, expect to start over.
