OK, I understand what you mean now. kiss_fft is a separate packaged I
merged into Speex, but which I haven't yet fully converted to use the
Speex functions/macros.

Try updating svn again. I just found out that EXTEND32() and EXTRACT16()
were actually unsafe due to a pair of () missing around the argument. I
also fixed a few minor things. Tell me if it works now.
