Unsure what it is that upsets it so much, but when linking
both sndfile and fftw dynamically, the linker gets confused
and thinks that fftw is importing sf_close from the blender
binary (which makes *NO* sense) leading to a start-up error.
Generating the import library from the .def file using the
ms lib tool creates an import library that works fine.
Note these are intended for platform maintainers, we do not intend to
support users making their own builds with these. For that precompiled
libraries from lib/ should be used.
Implemented by Martijn Berger, Ray Molenkamp and Brecht Van Lommel.
