In addition, the following `C99` features are explicitly allowed:
- `//` comments, as required by |style-comments|;
- - the `_Bool` type.
- - logical lines may contain up to 4095 characters;
+ - Mixed declarations and statements in a block;
+ - Variadic macros `(..., __VA_ARGS__)`;
+ - Trailing comma in `enum` lists;
+ - `_Bool` type (for `bool`, `true` and `false`);
+ - `__func__` predefined identifier;
+ - `inline` functions (use `static inline` for portability);
+ - Compound literals `(type){ initializer-list }`;
+ - Logical source lines up to 4095 characters.
Platform-specific code may use any newer compiler features supported on that
platform.
