Érico NogueiraandRich Felker 9a40e842df define __STDC_UTF_{16,32}__ macros
these macros are used to indicate that the implementation uses,
respectively, utf-16 and utf-32 encoding for char16_t and char32_t.

Rich Felker 0f47367751 add stdc-predef.h for library-level predefined macros
modern compilers (for gcc, versions 4.8 and later) automatically
pre-include <stdc-predef.h> to obtain the values of certain predefined
macros specified by ISO C but which reflect properties of the library
implementation, not just the compiler. provide values indicating that
wchar_t is Unicode-encoded and that Annex F (IEEE floating point) is
supported unless the compiler indicates otherwise.

based on patch by Masanori Ogino.
