My beef about it has nothing to do with binary-size concerns, although
that is an interesting angle. (I wonder whether marking a variable
PGDLLIMPORT has any negative effect on the cost of accessing it from
within the core code?) Rather, I'm unhappy with spreading even more
Microsoft-droppings all over our source. If there were some way to
just do this automatically for all global variables without any source
changes, I'd be content with that. That would *really* make the
platforms more nearly equivalent.
