Hi Alexandre,

Thanks for fixing this.

There is one patch from Mike to define type __ibm128 even without
IEEE 128-bit floating point support, it's at the link:

I would expect this issue would be gone if the adjustment on the
support of type __ibm128 gets landed in future.

So maybe we can just xfail this for longdouble64?  What do you
