Enum Dialect 

pub enum Dialect {
    Iso,
    Gnu,
}

Whether the GNU extensions that need a plain spelling are switched on.

GCC draws the same line between -std=c99 and -std=gnu99: everything spelled with a double underscore (__typeof__, __attribute__, __builtin_*, __extension__) is available either way, because those names are reserved and cannot collide with a user’s own; only the plain spellings — typeof, asm — need the GNU dialect, and only there is a feature of a newer revision accepted without a diagnostic (GCC takes _Static_assert in gnu99).

See doc/gnu-extensions.md in the repository for the whole catalogue.

Variants

Iso

Strict ISO C: c89!, c99!, c11!, c17!, c23!.

Gnu

ISO C plus the GNU extensions: gnu89!, gnu99!, gnu11!, gnu17!, gnu23!.
