-;;; 5 = sbcl-0.6.8 has rearranged static symbols.
-;;; 6 = sbcl-0.6.9, got rid of non-ANSI %DEFCONSTANT/%%DEFCONSTANT stuff

-;;; 8 = sbcl-0.6.10.4 revived Gray stream support, changing stream layouts.

-;;; 17 = sbcl-0.pre7.38 (merging many changes accumulated in
-;;; the sbcl-0.pre7.37.flaky5.* branch back into the main branch)
-;;; got rid of byte compiler, byte interpreter, and IR1
-;;; interpreter, changed %DEFUN and DEFSTRUCT, changed the
-;;; meaning of FOP-FSET, and changed the layouts of various
-;;; internal compiler structures (e.g. DEFSTRUCT CLAMBDA)
