> This issue is very similar to STDCXX-415. The __rw_itoutf8() function and __rw_utf8toucs4()
functions are nearly the same and both are found in the same area of include/loc/_localedef.h.
It appears that something has changed that has moved the warning. Perhaps we should consider
fixing both functions or just silencing the warning.
