No. And it would be a truly lousy idea to try to do so. The word "Modularization" comes to
mind.

You could pass pointers to these variables in, but frankly, it strikes me as exceptionally
poor practice to do so. If the DLL needs state, the state should come in via a pointer to
some class that defines the DLL context.

The usual reason for this question, by the way, is most often trying to partition
poorly-written code into a DLL, where the poorly-written code uses global variables. The
way to tell it is poorly-written is that, guess what, it accesses global variables.
Putting the code in a DLL just makes the defect obvious.
