For variables, you will need an explicit __declspec(dllimport) on
each variable that you are *importing*.

Typically this is done like thus:

#define FOO_DECLSPEC __declspec(dllimport)

And you have to use that macro in front of every exported variable.
We insert this code in the header files with a simple post-processor
for the variable types we actually export (mostly const char*, but a
few others).
