Thanks for the help. It really helped me out.

BTW; it seems to be an issue not only for Ada-programs, but for some
other "normal" C++-programs as well. I have one aplication that
compiles and links without problams, but it crashes when not defining
LD_ASSUME_KERNEL=2.4. We are looking into that now, and it is probably
a matter of doing things that have always been questionable (like
terminating non-existing threads) but happened to work (by luck) with
the old threading model, but not with the new one.
