Would you mind running it again with the default flags (-O2)? We don't have comparison points with these non-standard flags.
OK, here are the results with only -O2. All the errors in chapter cd are due to a build problem on my machine (the test programs cannot find spprt13.ads). Altough I already provide a linker option to increase stack size to 40MB there is still one program failing in a stack overflow.
