[PD-dev] fftw3 (partconv~ ) and PD 0.39

[Hans-Christoph Steiner]

I don't know the particular problem there, but if you send me the  
source, I could try adding it to Pd-extended and building it with  
MinGW.

Also, there is a patch to make Pd itself use FFTW3.  It looks pretty  
straightforward to apply and compile, but I haven't tried it.
