"Does this imply there isn't much optimization in GNAT yet"

If you write C level code, then you will get exactly the same level of
optimization you would from C.

If you write code full of tagged types, pointers to unconstrained arrays,
slices, aggregates etc. then of course you can't really compare the
generated code with C.

There are many improvements we can make to the code quality for these
higher level Ada constructs, and we are working away on them :-)

I don't know why you didn't get the warning about an uninitialized
variable, I have certainly see
n this working in some cases. Perhaps Richard Kenner can explain this.
