Well -- there are previous ones and they appear up to date. I don't
want them to be replaced: I'm quite confused that Gnat thinks it
necessary to recompile the standard library at all.

Good idea: I'll try it some time this week. I don't think though, that
Gnat actually doesn't see the standard library in that installation:
It can compile the projects without '-a' well enough (and AFAIR
without recompiling the standard library). If it didn't see the object
files of the standard lib I'd expect the linking step to fail, or
wouldn't it?

Hm. I don't understand the significance of this, but I'll have a look
in the gnat_ug again and think about it.

But wouldn't that mean, that I wouldn't be able to compile _anything_
without '-a'? But I can ...

But thanks -- I'll do more research in the directions indicated.
