There's a related (but slightly different) problem for F128 suffixes:
auto f = __FLT128_MIN__;
f128.C:1:10: error: unable to find numeric literal operator ‘operator""F128’
The macros for the F128 constants all end in a F128 suffix, which the C++
compiler doesn't understand at all, for any -std mode.
Either the macros shouldn't be defined for C++ or (preferably) they should work
correctly, maybe when __extension__ is used. This would allow libstdc++ to
define std::numeric_limits<__ieee128> for powerpc64le.
