Branch: HEAD
Tag: (none) 
Log:
More (and hopefully final) fixes for access.

        * kaffe/kaffevm/access.c
        (checkAccess): Simplified to the maximum according to Sun's VM
        spec we must not check for specific inner classes flags.

        * kaffe/kaffevm/classMethod.c
        (addInnerClasses): Do not merge inner class access flags with the
        class flags.

        * libraries/clib/native/Class.c
        (java_lang_VMClass_getModifiers): Return the right access flags
        depending on what we are asked and whether the class is nested.

        * test/regression/TestSerialFields.java,
        test/regression/TestSerialVersions.java: Removed private modifier
        to be able to run the tests (as for JDK).
