+changes in sbcl-0.7.8 relative to sbcl-0.7.7:
+ * A beta-quality port to the mips architecture running Linux,
+ based on the old CMUCL backend, has been made. It has been tested
+ on a big-endian kernel, and works sufficiently well to be able to
+ rebuild itself; it has not been tested in little-endian mode.
+ * fixed bug 120a: The compiler now deals correctly with IFs where
+ the consequent is the same as the alternative, instead of
+ misderiving the return type. (thanks to Alexey Dejneka)
+ * fixed bug 113: Logical pathnames are now dumpable (the logical
+ host is resolved at load-time, throwing an error if it is not
+ found).
+ * fixed bug 174: FORMAT's error message is slightly clearer when a
+ non-printing character is used in a format directive.
+ * fixed several bugs in compiler checking of type declarations, i.e.
+ violations of the Python "declarations are assertions" principle
+ (thanks to Alexey Dejneka)
+ * fixed several bugs in PCL's error checking (thanks to Gerd
+ Moellmann)
+ * fixed bug in printing of FILE-ERROR (thanks to Antonio
+ Martinez-Shotton)
+ * fixed bug in compilation of functions as first class values
+ (thanks to Antonio Martinez-Shotton)
+ * The compiler's handling TYPE-ERRORs which it can prove will
+ inevitably happen at runtime has been cleaned up and corrected
+ in several ways. (thanks to Alexey Dejneka)
+ * fixed bug 181: compiler checks validity of user supplied type
+ specifiers
+ * cleaned up code flushing in optimization: Function calls which
+ should signal errors for safety purposes (e.g. which ANSI says
+ should signal errors when their arguments are of incorrect type)
+ are no longer optimized away.
+ * incremented fasl file version number, because changes in the
+ implementation of sequence functions like COERCE have old
+ internal utility functions like COERCE-TO-SIMPLE-VECTOR (used
+ in old inline expansions) to become undefined
+
