Add support for testing __STDC_WANT_IEC_60559_TYPES_EXT__
This macro is defined by TS 18661-3 for supporting the _FloatN and _FloatNx types, as well as the functions suffixed with fN. * bits/libc-header-start.h: (__GLIBC_USE_IEC_60559_TYPES_EXT): New macro. * include/features.h: Describe __STDC_WANT_IEC_60559_TYPES_EXT__. * manual/creature.texi: Likewise.
