sbcl-1.3.16 released

Dear all,

I have just released sbcl-1.3.16.

This month's release sees relatively few directly user-visible changes
(listed at the end of this message), but a substantial amount of work on
tidying up the garbage collector, resulting in a ~5% decrease in GC
times.  There is an isolated report of a garbage collection problem on
the -devel mailing list; if anyone can reproduce a problem, as ever,
please report it as soon and as completely as possible.

Best wishes,

Christophe

changes in sbcl-1.3.16 relative to sbcl-1.3.15:
  * optimization: various small tweaks give around 5% faster garbage
    collection 
  * bug fix: better detection of when an impossible code path does
    not need a warning.  (lp#1668619)
  * bug fix: stronger attempts to disable position-independent
    executable building.  (lp#1668986, patch from Mark Wright)
  * bug fix: OPEN :IF-EXISTS NIL signalled a condition on Windows.
    (lp#1674437, reported by Jan Idzikowski)
