Bug#812995: yorick-ynfft: FTBFS with libnfft version 3.3

[Ghislain Antony Vaillant]

Package: yorick-ynfft
Version: 1.0.2-2
Severity: important

Dear Maintainer,

This source package fails to build with the latest release of libnfft
available in experimental. The relevant portion of the build log is
available below.

Version 3.3 introduced some API breaking changes in the signature of the
public structures.
