Thankyou for your help. The code example previously sent was providing an overview of the code layout (transitions removed). Adding transitions shows the problem under vc2003 e.g:
Please see the attached code, tested with VS2008. I introduced a level of indirection with the B0Dummy & C0Dummy states, declared in the M.hpp header. The trick is to have these states post an event in their entry action and then use a custom_reaction to immediately transition to B0 & C0. This works because now the transition target only needs to be mentioned in the cpp. Yes, the definition of two additional states & 2 events is a bit cumbersome, but this is sort of a worst case. E.g. it would have been much easier to implement A2 & A3 in their own CPPs, because there you'd only have to replace a transition with a custom_reaction.
