X-Git-Tag: 3.0.0~87^2~20

tests: define GVDLL to ensure correct storage-class attributes

An upcoming commit will change the storage-class attributes to be
controlled by the GVDLL symbol in cgraph.h.

Without this change, errors like this would occur when building the
test examples:

demo.obj : error LNK2019: unresolved external symbol Agdirected referenced in function main
