parameter.
* include/bits/boost_concept_check.h: Add pragmas to disable
-Wunused-local-typedef warnings.
* include/bits/codecvt.h (codecvt_byname<char16_t, char, mbstate_t>)
(codecvt_byname<char32_t, char, mbstate_t>): Remove name of unused
parameter.
* include/bits/locale_facets_nonio.tcc (time_get::do_get_weekday)

variables.
* include/std/bitset (_Base_bitset<0>::_M_getword): Remove name of
