when I declare

   type month_type is range 1 .. 12;
   for month_type'Size use 4;

   m: month_type := 1;

the compiler chooses 8 (following the rule
"Object_Size must be 8, 16, 32, or multiple of 64"
I guess.)

   TIO.put_line("m's size: " & Natural'image(m'size));

prints

m's size:  8

Tried with GNATs. Do other compilers choose smaller
representations?
