I guess the problem is that MyClass::I is not included in the
precompiled dictionary by default. If this is true, this is
already solved. Cint and rootcint does not make dictionary for
nested classes and nested typedefs by default. Adding '#pragma
link C++ nestedtypedef;' in MyClass.h will enable making
nested typedef information.
