No GNAT is written in Ada. Now that depends what you count. As you
probably know GNAT is part of GCC which is written in C. So most
accurately GNAT frontend and middleend (expander) are written in Ada.

Now most of the GNAT runtime is written in Ada, but part are in C which
is unavoidable to get proper values from the OS (such as constants for
example).

As you see the answer is not simple.
