Hi,
I have two question about fftw.info and in particular about two of the compilation flags:


1) what is the "real" meaning of the --enable-float flag?

Tells it to build a single precision (32 bit) library.


2) why the --enable-altivec options is omitted?


Because not everyone has a G4 or G5, and the thought is to have the package build exactly the same on every system (including G3s).
