CXXOFLAG_MAKE_TYPEDEF_charn_t

#define CXXOFLAG_MAKE_TYPEDEF_charn_t   0

Makes the reserved names char16_t , char32_t available via typedefs or named types.When in C++03 mode, if this macro is enabled, <cxxomfort/cuchar.hpp> will set up the names char16_t and char32_t as typedefs to uint16_t and uint32_t respectively, thus making them integral integer types, instead of declaring our own char16_t and char32_t types.
The former also follows how the names are set up in eg.: GCC in C++0x (not C++11) mode.
