+ * 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
