10.2.13 K&R Symbols

Two other syntactic symbols can appear in old style, non-prototyped C code 1:

      1: int add_three_integers(a, b, c)
      2:      int a;
      3:      int b;
      4:      int c;
      5: {
      6:     return a + b + c;
      7: }

Here, line 2 is the first line in an argument declaration list and so is given the knr-argdecl-intro syntactic symbol. Subsequent lines (i.e., lines 3 and 4 in this example), are given knr-argdecl syntax.
