//Cpdpfsmfactory.cpp(22...) : warning C4355: 'this' : used in base member initializer list
// these warnings are benign unless the designed usage of SpudFsm changes such that SpudFsm is used
// as a base class to something else, in which case this code will have to change IFF the this pointer
// passed is used in the states c'tor. Currently, the pointer is just stored.
// In V9, e32def.h turns this warning off.
