Subject: Keywords vs identifiers
Date: Thursday, 23 Jan 2020, 11:20:28

In C a keyword is an identifier that has special meaning.
For example (this list is NOT complete):

  break, case, char, continue, default, do, double, else,
  enum, extern, for, if, int, long, return, sizeof,
  static, struct, switch, typedef, unsigned, while

Cxref treats all identifiers (including keywords) the
same.
