Subject: twopigen: MSBuild: define GVDLL to ensure correct storage-class attributes
X-Git-Tag: 3.0.0~84^2~16

twopigen: MSBuild: define GVDLL to ensure correct storage-class attributes

An upcoming commit will change the storage-class attributes in
globals.h to be controlled only by the GVDLL symbol, not also by the
WIN32_DLL symbol.

Without this change, errors like this would occur:

twopigen.lib(twopiinit.obj) : error LNK2001: unresolved external symbol _Ndim
