Hi Dave. This one and the next one are the very same issue, caused by my fix
for libstdc++/31117.
I would ask you to help me with config/locale/generic/c_locale.cc on hppa. I
would ask you first to check separately the various tests in 12.cc and see
which one is failing, float, double, long double or all of them (I expect
integers to be all fine). I think float is the most tricky to get right. If I
remember correctly, for float, in c_locale.cc hppa ends up using the check:

        if (fabs(__d) > numeric_limits<float>::max())
        __f = __builtin_huge_valf();

on the d:

       double __d = strtod(__s, &__sanity);

and therefore you should check that why a very large __s doesn't lead to a __d
which doesn't pass the check above. More generally, you should tell me whether
hppa behave as expected wrt the various __builtin_huge_val* builtins: the
various strtof, strtod, strtold, sscanf should return floating point values up
to __FLT_MAX__, __DBL_MAX__, __LDBL_MAX__, or, +INF, which should be the same
as __builtin_huge_valf(), __builtin_huge_val(), respectively,
__builtin_huge_vall() and should compare bigger.
