Subject: add stdc-predef.h for library-level predefined macros
X-Git-Tag: v1.1.15~1
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0f47367751a4baca80ef4f5ab11dbb9b6d7e8bdd;p=oweals%2Fmusl.git

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.
