You can download PDa and look at the source. But it is so trivial to
change the behaviour (in some cases), that it is not even necessary.

Just delete the xxx_setup() function from the pd source and move all
the xxx_* code into a separate file and treat it as an external.

But then, there are some things which make this a bit more complicated in
some cases. e.g. as Thomas noted if you want to reuse code in several
"internals/externals".
This might be important in the SIMD case, but maybe you can factor
out standard operations into macros and reuse those.
For PDa I had to come up with a workaround for sine tables that are used
by some oscillators.

And, I just made the signal processing objects external up to now, so
I don't know what problems will arise with others ...
