commit 850f3578fdeca2370fb27d2f319dc8354bd51774

    Fix definition of INFINITY and add NAN/HUGE_VAL[F]
    
    v3: change __builtin_nanf() to __builtin_nanf("")
        This doesn't work yet, but it was agreed to commit as-is with the logic
        that "broken" is better than "completely missing" and this should be
        fixed in clang.
    
    v2: use __builtin_inff() and also add nan/huge_val definitions
