No, GNAT allows up to 64 bit in all platforms supported. Unlike floating
point integer can easily expanded. Most CPU's have a so called "Carry" flag
for integer expasion. This comes from way back 8bit times where integer
expansion was esential.

Of corse a 12 bit type on a 32 bit CPU will only be 12 bit in a packed array
or a packes record. Otherwise the compiler will expand the type to render
better performace.
