You should not need the definition of __STDC_WANT_IEC_60559_BFP_EXT__.
The point of defining __STDC_WANT_IEC_60559_TYPES_EXT__ here is, I
presume, to make the compiler-provided float.h define macros for
_Float128 (_GNU_SOURCE, defined by default, ensures that glibc-provided
headers declare everything expected for the new type). The only thing
__STDC_WANT_IEC_60559_BFP_EXT__ does for the compiler-provided float.h is
make it define CR_DECIMAL_DIG, which is not used by glibc.
The patch is OK with the definition of __STDC_WANT_IEC_60559_BFP_EXT__
removed.
