OK how about;

token_grabbing_function()
{
  for (;;)
  {
    while (is_white_space(c = getchar()); /* skip it */

    /* So, c contains a non-whitespace character */

    if (c == comment_delimiter)
      while (c = getchar() != other_comment_delimiter); /* skip it */
    else
    {
      deal_with_the_token_properly_and_return;
    }
  }
}
