[speex-dev] Fixed-point in CVS

I have been doing some work on a fixed-point port and it is now in CVS.
All of the CPU-intensive parts should now be using only integer
operations. Now, it's in a state where even non-coders can help: find
bugs. With all these changes, there are probably several bugs and some
may show up only under specific circumstances. Please test to see if the
fixed-point behaves the same as the floating point, under all kinds of
modes, all kinds of files, mixing versions for encoder and decoder, and
so on. Please report any case where the new version behaves badly
compared to other versions. 

Last thing: to enable the fixed-point, you need to compile the
FIXED_POINT defined (sorry, no configure option yet).


P.S. I'm also interested on speed reports on CPU's without an FPU.
(expect the fixed-point to run slower on x86)
