Due to a charming DEC assembler bug, the mieee switches did not
work well enough to be usable on alpha-osf up to osf-4.0 or so.
It would be a disaster to make ieee the default on those systems.
If you have a working assembler now, the ieee modes should be tested.
At the time, it was so hard to make anything at all run that it
would be a miracle if it really worked.
