    libstdc++: Avoid using __float128 in strict modes
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/26_numerics/numbers/float128.cc: Check
            __STRICT_ANSI__ before using __float128.
            * testsuite/std/concepts/concepts.lang/concept.arithmetic/floating_point.cc:
            Likewise.
