One way of getting a correctly running program is to fix GNAT yourself.
For the runtime library this often isn't hard.

I didn't follow the thread, so I don't know which version it was - gcc-3.3?

It is tedious, but when you are trying to find out where things are going
wrong in a mass of code you are unfamiliar with (like the runtime library),
it can be quite helpful.
