> Returning unconstrained objects from functions requires the so-called secondary stack in GNAT. If you want to use it you need the files s-secsta.ad(s|b) and s-stoele.ad(s|b). (Then you cannot call your run time system a "zero footprint" system anymore as the footprint is > 0)
I took a look in these files, at first it would be a good try. But you made a good point... if I were to use the secondary stack I could not call my rts a "zero footprint" (so I thought twice...)
> The ATmega2560 is relatively big, you probably dont have to care. Unconstrained arrays are nice syntax sugar. If you are short on RAM or flash (I always am) you don't want to use that feature, however.
Now I am not short of RAM and flash, but I'm sure I will be soon. You are right.
