Richard,

Here is another minor diff to the diassembler to get certain conditional
branches instructions correct...

Also, I noticed that gcc.tar.Z is out of date with respect to gcc.tar .
When I go to get these files, should I go ahead and replace the compressed
version with a newer one or should I leave it alone? Likewise, should I try and
make a split version on prep?
