* fixed some bugs revealed by Paul Dietz' test suite:
** interval arithmetic during type derivation used inexact integer
to single-float coercions.
+ ** arithmetic operations involving large integers and single
+ floats give the same results in compiled and interpreted code.
+ ** deriving the result type of COERCE no longer signals an error
+ if the derived type of the second argument is a MEMBER type
+ containing invalid type specifiers.
+ ** ADJOIN with constant NIL as second argument works correctly.
+ ** FUNCTION-KEYWORDS was called SB-PCL::FUNCTION-KEYWORD-PARAMETERS.
changes in sbcl-1.0.18 relative to 1.0.17:
* minor incompatible change: SB-SPROF:WITH-PROFILING now by default
