10.2.14 K&R Symbols

Two other syntactic symbols can appear in old style, non-prototyped C code 43:

 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.
