Subject: [PATCH] gml2gv: MSBuild: 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 cdt.h.

Without this change, errors like this would occur:

gv2gxl.obj : error LNK2001: unresolved external symbol _Dtoset
