Enum Deduction 

pub enum Deduction {
    Auto,
    AutoType,
}

Which of the two spellings asked for a deduced type.

They deduce the same type and are not the same specifier: gcc names the one that was written in everything it says about a declaration, and C23’s is in scope inside its own initializer while GNU’s is not.

Variants

Auto

C23’s auto, which is the storage class keyword with no other type specifier next to it.

AutoType

GNU’s __auto_type, which C23’s is modelled on and which every dialect has.
