Yes, you can download "c++-interface" in 

"ftp://ftp.cdrom.com/pub/languages/ada/compiler/gnat/distrib/docs/"

This article has an example that shows how to interface a C++ class
from Ada programs. I still try to interface an Ada tagged type from
C++ programs but I have not successed yet.

No, you still can use the CC (SGI's C++ complier) and GNAT.
However, I has to reminder you that GNAT's C++ LOW-LEVEL interface
capability is defined for third party venders not for programmers.
If you want to do this kind of work by youeself, I'll say it is not
easy especially for large system.
