sbcl-1.4.16 released

Dear all,

I have released sbcl-1.4.16, and uploaded the source to sourceforge.  I
have also uploaded an x86-64/Linux binary, but I have to report that
unusually I have built this on a relatively modern system rather than my
Debian squeeze virtual machine, because of a disagreement with texinfo
versions.  If this inconveniences anyone, please let me know and I will
look into linker scripts to sort out building binaries on modern systems
that will run on ones with older ones.

The brief user-visible changelog is shown below; this month's
development mostly focussed on build processes improvements and an
exploration of possible optimizations of MULTIPLE-VALUE-BIND.

Best wishes,

Christophe

changes in sbcl-1.4.16 relative to sbcl-1.4.15:
  * minor incompatible change: ENSURE-DIRECTORIES-EXIST no longer establishes
    a CONTINUE restart in case of an error.
  * minor incompatible change: Defining macros (DEFVAR, etc) which require a
    symbol as the name will fail to macroexpand if given a non-symbol.
  * enhancement: the unexported restart names SB-{ALIEN,FASL,IMPL,PCL}::RETRY
    have been replaced by SB-EXT:RETRY.
