bitset (bitset(const char*)): Implement DR 778 in debug-mode too.

2008-05-29  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/debug/bitset (bitset(const char*)): Implement DR 778
	in debug-mode too.

	* include/bits/cpp_type_traits.h (__is_integer): In C++0x mode
	deal with char16_t and char32_t.
