Cast increases alignment problem.

In bits/stl_alloc.h line  364:
       static char*                  _S_start_free;
Should be declared pointer to _Obj, otherwise places such as
line 503:             
  ((_Obj*)_S_start_free) -> _M_free_list_link = *__my_free_list;
whinge (rightly) that cast increases alignment.
>How-To-Repeat:

>Fix:
Change declaration of _S_start_free and then use appropriate member.
