Hi FX,

I am not sure the logic is correct for POWER (old style) where we have
a 16-byte long double made up from two 8-byte doubles, which is not
__float128 (IFmode), see

https://gcc.gnu.org/pipermail/fortran/2021-November/056912.html

I have a proposal: Since I am currently trying to unravel this
on the power-ieee128 branch, I would like to take this on,
if that is fine with you.

Best regards

	Thomas
