Hi,
We compiled libvorbis with vc6 enviroment.
We've discovered that changing float to int conversion results in a 4% speedup
on a benchmark we've come with on pentium4 3GHz.

We'd like to submit the code.
We haven't checked it on AMD.
Yet, as you can see in the code, it shouldn't be a problem.
Should we think of other machines except for AMD/Intel machines?

Tal&Adir

P.S.
you can diff the files in zips
