I've read on the fly the code used and I've not seen any line of
assembler code. Perhaps the C-code has tuned thinking in x86.

I've found a microsoft f-90 compiler. I've tried to compile it this
afternoon but it gives me some errors, I think easy to solve. The
compiler requires interfaces for most fft routines because first
parameter 'a' is a target !? :-(
I have no many time. But I'll be on work.
