I tried out the Gentoo patch which builds the library into a shared
onject (and it works fine), but I decided against it because (1) the
djbfft code is not going to change and the API is stable anyway so
static linking should be just fine and (2) djbfft is chosen for its
high performance and dynamic linking would be a drawback in this
regard. So I decided for building static libraries (the "normal" one
and an additional PIC-flavour), but this is subject to change.
Please check out: svn://svn.debian.org/svn/pkg-multimedia/unstable/djbfft

Yes, sure, why not!

This will be highly appreciated among distributors, I believe (given
that the performance drawbacks aren't too severe).

I'll see if I can find some spare time this week...

Hm, not at the moment, sorry. I am not that much interested in lossywav...
