From: Jonathan Wakely <jwak...@redhat.com>
The char16_t and char32_t types are automatically defined by the
compiler and do not depend on support in <stdint.h>. The char_traits
specializations depend on uint_leastNN_t but can be made to work anyway
by using the predefined macros, or as a last resort make_unsigned.
* include/bits/basic_string.h [!_GLIBCXX_USE_C99_STDINT_TR1]

_GLIBCXX_USE_C99_STDINT_TR1.
