Yes - this is just a bug in the FFTW configuration that we can't do much
about. It's just libtool telling you that the fftw library was installed
to a different path in the first place. It won't cause any problems.

I don't see this on my SP system, but I don't think it will cause any
problems. In theory, libtool has the capability to link all libraries
into the library you are creating (i.e. include the parts of libc we
need into libmd), but since I'm pretty sure your linker/compiler will
include libc at the link stage it should probably work. This is a
libtool bug ;-)

Sure. We're not using multithreading parallelization yet, but when it's
working I will be changing the compiler detection part to use the
threadsafe ones by default.
