* jode/expr/Expression.java.in (updateParentTypes): Call setType,
instead of merging the types. Other childs want to know about the
type change as well.
* jode/decompiler/LocalInfo.java (combineWith): Reorganized a bit,
but no changes.
* jode/expr/InvokeOperator.java.in (dumpExpression): Always print
the ThisOperator if a field is from a parent class of an outer
class is used. And always qualify the this operator if not
innermost.
2001-01-30 Jochen Hoenicke <jochen@gnu.org>
* jode/jvm/SyntheticAnalyzer.java.in (checkConstructorAccess):
Allow the special unifyParam to be the last parameter.

(openBraceClass) (closeBraceClass)
