I've never needed to use any /export flag. I'm using Visual C++ 2005 
Express Edition Beta (because it was free as in beer), which looks like 
a limited version of VS8.
If the project is set up to make a dll, I think the only other thing to 
check is that you have MSW defined somewhere before you include m_pd.h, 
because VS defines _MSC_VER_ and _WIN32, but not MSW or NT.
