  • Some more C23 features have been implemented: +
      +
    • Bit-precise integer types (_BitInt (N) + and unsigned _BitInt (N)): integer types with + a specified number of bits. These are only supported on + IA-32/x86-64 at present.
      • +
    • Structure, union and enumeration types may be defined more + than once in the same scope with the same contents and the same + tag; if such types are defined with the same contents and the + same tag in different scopes, the types are compatible.
      • +
    • The <stdckdint.h> header for checked + integer arithmetic.
      • +
    +
    • +
  • In addition to those C23 features, there are new command-line + options -std=c23, -std=gnu23 + and -Wc11-c23-compat. These are equivalent to the + previous options -std=c2x, -std=gnu2x + and -Wc11-c2x-compat, which are deprecated but remain + supported.
