This is way old; get gnat 3.13p

Is this at the command line, or in some GUI? At the command line, the
gnat compiler is much more informative; for one thing, it tells you
what file it is compiling when it encounters the error.

The error message is saying that you cannot override language defined
units.

There is an option in gnat to let you do just that; consult the user
guide. But you should typically not be doing that.


Post the code you are trying to compile, so we know what you are
doing, then we can help more.
