[PD] [PD-announce] jl lib

[Joseph Larralde]

Hmmm, that's what I was fearing.
In my c++ lib I read the buffers/tables contents passing them as 
pointers to floats/doubles.
I'm not sure I can do this anymore with t_words, without either copying 
the whole buffer to provide a simple pointer to it,
or modifying the c++ API in some other way, using getters ore some other 
trick.
