I acknowledge that it is helpful to have foreign (e.g., C) semantics for interfacing. But is there any need for a general Boolean size, or only for "Boolean (8)", "Boolean (16)", etc.?
The standard way to create an array of 1 bit booleans is with 'packed'. i.e. "packed array [0..31] of boolean" could occupy one 32 bit word. No need for C bitfields.
Indeed. But "Boolean (32)" doesn't create 32 1-bit Booleans but rather a single 32-bit variable with roughly Boolean semantics ("roughly" meaning that 0 is FALSE and all other values are TRUE). There is no way to achieve that directly using "packed" and the standard Boolean type.
