A good thing might be that Pd is already, at least experimentally, compilable with double precision, as I found out in its src/makefile.gnu. I managed to run it this way and did some basic maths. Calculations seems to be done correctly but their display is still truncated scientifically. And I had to use the internal FFT library instead of FFT3W or it couldn't compile. But at least it is not a start-from-a-blank-page task :).
Are you using katja's Pd double repo?
If you're just changing the value of t_float, then there are a number of objects (like [osc~]) which are not computing 
the correct output.
