Thanks for your contribution, but I'm somewhat confused about it.
1) Why do we need to call "make clean"? Won't the next ./configure
touch exactly the pieces that have to change, such that the
next "make" rebuilds exactly what needs to be rebuilt and reuses
In case that doesn't work reliably on libfftw, we can't count on
"make clean", either. Instead, we should make copies of the source
tree before the build. Look e.g. at src/glib.mk where we use that
technique to separat the native (bootstrapping) build from the
2) Won't the latter "make install" commands overwrite the libraries
for the former installations. I mean, there's no prefix or suffix
to the fftw lib. All 3 versions seems to produce (and thus overwrite)
a "libfftw3.a" and a "libfftw3_threads.a" file.
