You can use both __ibm128 and __ieee128 in one program, so it isn't an ABI change. Only the default of what "long double" means changes. And we have been there before, there is the "e" mangling as well...
For Fortran, it is an ABI change unless we define an additional KIND number for __ieee128. Best regards Thomas
