Thanks Luke, but please don't go to any special effort on my behalf.

Having thought about the situation, I'm getting nervous once again about
the "special" :-( situation around Ada compilers given that I'm not
sure where some of this code might be used in the future.

My current thinking (as of this morning :-)) is to maybe write the low
level stuff in C++ (which is the code more likely to be used elsewhere)
and to do the high level stuff in Ada.

The problem is that I don't have any experience combining C++ and Ada
code in the same binary; in the past, I've only ever called plain C code
from Ada.

Does anyone know of any issues combining C++ and Ada code in the same
binary when using gcc and binutils ? Are there any conflicts with
exceptions for example ?

The primary use of such binaries would be on a Linux x86 (and maybe
ARM) platform.

Thanks,

Simon.
