Function accumulate_token calls xrealloc with NULL pointer if
accumulator has just been initialized. I made the code work by
replacing this definition

----------------------------------------------------------------
/* Buggy! */

void
initialize_token_accumulator (accumulator)
     struct token_accumulator * accumulator;
{
  (accumulator -> length) = 0;
  (accumulator -> index) = 0;
  (accumulator -> tokens) = NULL;
}
----------------------------------------------------------------

with the following definition:

----------------------------------------------------------------
void
initialize_token_accumulator (accumulator)
     struct token_accumulator * accumulator;
{
  (accumulator -> length) = 1;
  (accumulator -> index) = 0;
  (accumulator -> tokens) = (char **) (xmalloc(sizeof(char *)));
}

Thank you.
