MODES_TIEABLE_P yes or no

[Andy Hutchinson]

This is tremendous!

Can somebody check out a few real embedded application? So we can see if 
there is any I/O hiccups and get a feel for code improvement? Something 
very "char/byte" orientated plus some floating point?? oh yes - it 
should be run and see if it works rather than just compile/simulate.

I have found no issues but I have other optimisation in my setup that 
now prevent a true comparision.
