I tried both combinations with both GNAT versions. The -O1/O2 switches makes no difference on the size. The object code of the main program is less than one KB, so most of the linked program must come from some precompiled library, which is not affected by the compiler switches.

Tried this one also now. The 3.15p GNAT don't have it. The 2014 GNAT still produces a 195 KB executable.
