    ! memory allocation wrappers updated to better mimic behavior
      of standard malloc()/realloc()/free()/calloc()
      It is particularly important to let free() silently accept NULL
      argument. [I chose zero size allocations to return NULL.]
    ; Cricital update for anyone using libcurl 7.36.0 or newer
