Experimental Physics and Industrial Control System

I have run into this before. I my case, I was lucky and got by with not including EPICS callback.h in a source file where it was not really needed. For EPICS, putting a symbol with a name as generic as "CALLBACK" into the global namespace is pretty much calling for clashes.

I think the issue is header ordering, though rather than the
usual dllimport/export, it is a conflict with CALLBACK.
I can't recall having to resolve this before, and the build output
isn't very helpful. I don't see a reference to the line
in pdbsingle.cpp through which dbghelp.h is included.
So I don't know where to start moving things around.

I know that this isn't the only issue. There are some dllimport/export
issues as well. I have a process for sorting through these though.
