Upcoming changes

[Raymond Toy]

In the next day or two, I will be checking in some changes for Unicode
that makes the utf-8 reader much faster (2-3 times or so).  The other
formats don't see much change in speed.

However, to bootstrap this change you will need to do a cross-compile
using the unicode-string-buffer-branch.  Use boot-2009-10-1-cross.lisp
as the cross-compile script.  (Don't forget:  you need to do,
eventually, an x87 and an sse2 build.  Non-unicode isn't needed here.)

Once you finished the cross-compile, you can use that to build the
sources.  You can try this with the unicode-string-buffer-impl-branch
now, or wait until that branch is merged to the trunk.
