Why not __STDC_WANT_IEC_60559_TYPES_EXT__ (which makes GCC 7's <float.h> declare limits for _FloatN and _FloatNx types; not yet anything in glibc, until the float128 work is in)?
Sorry, I didn't know about __STDC_WANT_IEC_60559_TYPES_EXT__. I don't have access to the recent ISO C standards documents, which are not free.
(There are other feature test macros for ISO C extensions as well.)
Thanks, is there a list of these new macros somewhere? I might as well add them all now.
