* add stdc-predef.h for library-level predefined macrosRich Felker2016-07-031-0/+10
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.
