From 0f47367751a4baca80ef4f5ab11dbb9b6d7e8bdd Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sun, 3 Jul 2016 20:03:30 -0400 Subject: add stdc-predef.h for library-level predefined macros modern compilers (for gcc, versions 4.8 and later) automatically pre-include 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. --- include/stdc-predef.h | 10 ++++++++++ 1 file changed, 10 insertions(+) create mode 100644 include/stdc-predef.h diff --git a/include/stdc-predef.h b/include/stdc-predef.h new file mode 100644 index 00000000..f8cd4b89 --- /dev/null +++ b/include/stdc-predef.h @@ -0,0 +1,10 @@ +#ifndef _STDC_PREDEF_H +#define _STDC_PREDEF_H + +#define __STDC_ISO_10646__ 201206L + +#if !defined(__GCC_IEC_559) || __GCC_IEC_559 > 0 +#define __STDC_IEC_559__ 1 +#endif + +#endif -- cgit v1.2.1
