That's what I thought too. :-(

Out of curiosity, what compiler and RTOS? Your Ada vendor ought to have bindings
to the OS provided with the compiler.
Even without them, C bindings are trivial to write, once you get the hang of it.
Its certianly far less effort than a language port!
And I don't see how having a C++ port is that going to help you the next time
you port to a new system. Odds are you are actually *better off* right now with
the Ada sources than you would have been with C++ sources. At least the Ada
language itself is portable. C++ can't even say that much. The C++ porting guide
for Mozilla forbids using quite a few *core* language features (templates,
static constructors, exceptions, namespaces, among others) due to portability
issues. You can see
http://www.mozilla.org/hacking/portable-cpp.html for the whole list. If you *do*
port to C++, you'd do well to read and follow it.

Good. You at least need to be somewhat realistic about what you are getting
yourself into.
