Wait, so you think that the ultimate path here is that DMD becomes able 
to emulate 80-bit floats, *and then* is ported to another problem with 
the purpose of cross-compiling to x86?

I'm far from being the one to determine what path DMD development should 
take, but this strikes me as something nobody is asking for.
