The -fdefault-* family of options is broken.

The -freal-* family of options is broken.

The -freal-* family of options is less broken than the
-fdefault-* family of options.

Neither family of options can be fixed for all situations
that one might encounter.

These options should never be used (withi the possible
exception of porting from one precision to another).

I think I'm done here.=
