I might just rip out the relevant libDSP parts and put them directly into 
jack_convolve. Anyways, if you don't succeed in building with libDSP, you can 
still use the naive C implementation of the complex multiply-and-add function 
(see the README in libconvolve and the Makefile)..

jack_/libconvolve themself should work perfectly fine with newer gcc's..

Flo

P.S.: Maybe anybody has some ready to use optimized complex multiply-and-add 
function lying around? Let me know..
