In the new FFTW code, you have
char in_align = ((int) in) & 0xF;
char out_align = ((int) out) & 0xF;
with in and out declared as double*. I think this will produce a
warning on Alphas and other systems where sizeof (double*) != sizeof (int).
So probably this should use long instead? But even then, it is a bit
of a kluge. Is there any guarantee that a pointer will fit in a long?
Is there any better way to check the alignment?
Thanks,
jwe
