	* include/std/std_bitset.h:  Replace CHAR_BIT with __CHAR_BIT__, use
	numeric_limits for bits-per-word values.
	(_Base_bitset::_M_do_count, _Base_bitset<1>::_M_do_count):
	Use __builtin_popcountl instead.
	(_Base_bitset::_M_do_find_first, _Base_bitset::_M_do_find_next,
	_Base_bitset<1>::_M_do_find_first, _Base_bitset<1>::_M_do_find_next):
	Use __builtin_ctzl instead.
	(_S_bit_count, _S_first_one):  Remove.
	* config/linker-map.gnu (GLIBCPP_3.4):  Remove std::_S_bit_count.
	* src/Makefile.am (sources):  Remove bitset.cc.
	* src/bitset.cc:  Delete file.
	* src/Makefile.in:  Regenerate.
