release candidate for sbcl-1.1.8

Dear all,

As something of an experiment, after a very busy month of development
and a short freeze period, I'm making available a release candidate
rather than pressing directly ahead with the release: a number of
subsystems saw some moderately invasive changes, and while the
regression test suite we have exercises a lot of code paths, more
real-world testing would increase my confidence in the system.

Therefore, I would appreciate it if people could test the current HEAD
in the git repository, and verify that it functions as expected for
their workload.  I've put a tarball of the source code at
<http://www.doc.gold.ac.uk/~mas01cr/tmp/sbcl-1.1.7-116-g17dd0a1-source.tar.gz>,
and an x86-64/linux binary at 
<http://www.doc.gold.ac.uk/~mas01cr/tmp/sbcl-1.1.7-116-g17dd0a1-binary.tar.bz2>.

Reports to sbcl-devel (or to me personally), particularly of any
libraries or applications which do not seem to function as expected,
would be much appreciated; absent indications to the contrary, I would
hope to make the release early next week.

Best wishes,

Christophe
