You could always modify the compiler :)

You might want to look at user-defined boolean types here (it's sometimes a 
little confusing in Ada to distinguish between integer types and type Integer, 
character types and type Character, string types and type String, boolean types 
and type Boolean):

type Big_Boolean is new Boolean;
for Big_Boolean'Size use 32;
for Big_Boolean'Alignment use 4;

Conditions can be of any boolean type, so you can use this just like type Boolean:

B : Big_Boolean;

if B then ...

while B loop ...

exit Some_Loop when B;
