fastest wc program

Write the fastest program that counts the number of words and lines in a string.

Here's my solution

#include "stdlib.h"
#include "stdbool.h"
#include "stdio.h"

// macro that increments index, sets variables for the next stage, and
// gotos the label indexed by the current character
#define next(c, lc, iw) cnt = (c); lcnt = (lc); in_word = (iw); idx++; goto *(jmp_arr[(int)str[idx-1]]);

                             
int main(int argc, char** argv)
{
  /* test string */
  char* str = argv[1];
 
 
  /* normally this would be done as a sort of partial evaluation, but i can't for example generate an optimized function at runtime in C */
  void** jmp_arr;
 
  jmp_arr = malloc(sizeof(char)*256);
  int i;
  for (i = 0; i < 256; i++)
    {
      switch ((char)i)
        {
        case '\n':
          jmp_arr[i] = &&newline;
          break;
        case ' ':
          jmp_arr[i] = &&whitespace;
          break;
        default:
          jmp_arr[i] = &&character;
          break;
        }
    }
 
  // null character points to exit label
  jmp_arr[0] = &&terminate;

 
 
  int cnt = 0;
  int lcnt = 1;
  bool in_word = false;
  int idx = 0;
 
 // jump to label for first char
  goto *(jmp_arr[(int)str[0]]);
 
 terminate:
  printf("words: %i, lines: %i\n", cnt, lcnt);
  return 0;
 
 whitespace:
  next(cnt, lcnt, false);
   
 newline:
  next(cnt, lcnt+1, false);
 
 character:
  if (in_word)
    {
      next(cnt, lcnt, true);
    }
  else
    {
      next(cnt+1, lcnt, true);
    }
}

What is the matter with you? Is it really that satisfying to go online and try attacking the credibility of others? I'd rather you invest energy in contributing something insightful or original instead. You confuse familiarity with a set of standard functions with prowess.
