Required a custom build of the compiler for the library to work 
is rather inelegant imo.
However It might allow you to make progress the quickest.
Note that this only changes the type all ct-float-math is done at 
to double.
which means that know float and real will be double.
(Which is probably better then having float and double transform 
into 80bit reals)
