/* The first three groups, apart from '=', can appear in preprocessor
45
   expressions (+= and -= are used to indicate unary + and - resp.).
46
   This allows a lookup table to be implemented in _cpp_parse_expr.
47
 
48
   The first group, to CPP_LAST_EQ, can be immediately followed by an
49
   '='.  The lexer needs operators ending in '=', like ">>=", to be in
50
   the same order as their counterparts without the '=', like ">>".
51
 
52
   See the cpp_operator table optab in expr.c if you change the order or
53
   add or remove anything in the first group.  */
