STDCXX-226
* include/rw/_defs.h (_RWSTD_RATIO_DIVIDER): New macro defined the value
to divide the _RWSTD_{NEW|STRING}_CAPACITY_RATIO.
(_RWSTD_NEW_CAPACITY_RATIO): The value with floating point replaced to
integer value using multiplication with _RWSTD_RATIO_DIVIDER.
(_RWSTD_STRING_CAPACITY_RATIO): Ditto.
* include/rw/_specialized.h (__rw_new_capacity): Floating point
operations replaced to integer operations.
* include/sstream (_C_grow): Ditto.
* include/string (__rw_new_capacity): Ditto.
