The solution from this page seems to bring me a step further:
https://stackoverflow.com/questions/33423502/expression-did-not-evaluate-to-a-constant-c

so...
char tmp_compound[4+strlen(Get_Token_String(CYLINDER_TOKEN))];
becomes
char* tmp_compound = new char[4+strlen(Get_Token_String(CYLINDER_TOKEN))];

Now I'm left with new lnk errors of "unresolved external symbols"(?) in
povcore64d.lib(tracepixel.obj)
