説明

8e60adcaafbd5b6859f54879496e017dd218e541 implemented part of the paper, but missed "shall not contain a definition of a modifiable object with static or thread storage duration" from the removed text. e.g., we still diagnose this:

inline void f(void) {
  static int x; // warning: on-constant static local variable in inline function may be different in different files
}

This should be accepted in C2y mode and claimed as an extension in earlier language modes.
