Hello CLA-

In the past I have developed heterogenous programs comprised of Ada and 
C++ code linked together. These projects involved the use of gcc for the 
C++ and Green Hills AdaMULTI for the Ada code. For cases where C++ was 
the "main" program, Gren Hills provided 3 C functions that made the 
integration much easier:

rts_task_init()- registers a C thread with Ada run-time so that after 
this call Ada will see it as if it were an Ada task. This way the C code 
can call Ada code that might make a protected object call, task 
rendezvous etc and teh C thread will be suspended and restarted properly 
just as if it were an Ada task

adainit()- kicks off all Ada elaboration, initialization etc just as 
would happen at program start if Ada were the "main"

adafinal()- finalizes all objects just as would occur at end-of-program 
if Ada were the "main"

Does GNAT provide similar capability for cases where C++ is the "main"? 
Note that it may be that we will be using a C++ compiler other than gcc, 
I have heard that Ada/C++ integration is easy with GNAT if the C++ code 
is compiled with gcc.
