Improved speed with better bit-stream code, fixed a couple of minor arithmetic bigs. Reinstated the audio time-out tweak. Added automake support.

Got rid of the (now rather anachronistic) use of temportary files for the 1st-pass data and slotted in a faster bit-stream reading library.

Believe it or not, some essentially minor modifications to fix some subtle quantisation bugs that only showed up when I started creating high data-rate streams.

Fixed bug in SSE dist routines caused by changes in C (parameter no longer provided) and tidied stuff up a little more...

Made fast quantisation code robust. It is now perfect for all legal values for coefficients below 63 and gets than 0.1% wrong for big coefficients. Zoom zoom!

Slowly coming towards a release ... lots of untested code still !

Completed initial experiments with gradient descent. Solved problem with inaccurate fast integer quantisation calculations (for now.... maybe) and completed porting over of available MMX routines. There's really very little left in the code that can benefit from this. One or two more routines plus extending the fast MMX stuff to the other quantisation routines.

O.k. now the bugs are out some polish. First cut a faster C routines for quantization. The job is completely done yet - need to tidy up parameter usage vs. globals and do intra as well and non_intra. However, it works and its a lot quicker (mainly due to avoiding the dreaded integer divide (positively glacial on the x86).

Fixed some nasty and damn subtle bugs causing corruption of the fast motion compensation data. Took *ages* to pin down...

Found that wretched bug in the the assembler that was causing weird, rare, random misbehaviour. Guess who wasn't saving a modified register. Eeeeee-orrrr....

Wasted effort - further tuning of motion compensation search. Instad found my own and compiler bugs and gain .... wow ... and 8% speed-up for a days work. Should have worked on SSE code for the quantisation routines.
