+ * floatformat.c (floatformat_always_valid): Change type of last
+ argument to `void *'.
+ (floatformat_i387_ext_is_valid): Likewise.
+ (floatformat_to_double): Change type of second argument to `const
+ void *'.
+ (floatformat_from_double): Change type of last argument to `void
+ *'.
+ (floatformat_is_valid): Change type of last argument to `const
+ void *'.
+ (ieee_test): Remove redundant casts.
