[x264-devel] NOTE: Altivec/PPC port is broken

[Guillaume POIRIER]

Hello folks,

The different changes that have been made to the original C code lead
Altivec routines to stop matching the output of C code.
Here's what checkasm has to say about it:

x264: at least one test has failed. Go and fix that Right Now!

I shall fix it as soon as I can. Meanwhile, please stick to pre-GIT
versions of x264, which still work IIRC.
