Jules Maselbas	8b70486807	stdc-predef.h: prevent redefining __STDC_UTF_{16,32}__ macros ... Undefine any previous __STDC_UTF_{16,32}__ macros before defining them to prenvent any warnings of redefining macros. This happens as a result of some compiler versions defining the macros themselves.	2024-02-03 20:04:42 -05:00
Érico Nogueira	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.	2021-04-19 09:49:20 -04:00
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.	2016-07-03 20:03:30 -04:00
