For OpenBSD 4.5 and gcc 4.3, I managed to get rid of most of these
warnings. You can see my custom port at
http://sourceforge.net/p/gnuada/code/HEAD/tree/trunk/OpenBSD/current/lang/gcc/
relevant patches are here:
http://sourceforge.net/p/gnuada/code/HEAD/tree/trunk/OpenBSD/current/lang/gcc/4.3/patches/
For example:

I managed to pass the buffer length from Ada side to C code in
some cases. No idea did I do it correctly, but it seemed to work.

Same problem here. Ada runtime (or Ada in general) in gcc
is quite complex thing and I didn't have time to continue
working on the port, so I had to give up and hope that
someone else will continue.
