// 4, most of the SDK and CRT headers fail to compile (isn't that nice?).
// So, here we set the warning level to 3 while we compile the headers

// Use of pointer types with STL container classes generates this beauty,
// which is a warning because if the situation it warns agains is
// ever encountered, that code will fail to compile.
//
// The problem is that iterator classes define operator-> to return a pointer
// to the element type T of the container. When that element is itself a
// pointer, then the return type of is a pointer to pointer, which has no
// members or methods to invoke. So code like
//
// list<Foo*> l;
// list<Foo*>::iterator i = l.begin();
// i->f();
//
// will not compile, as the type Foo* does not have a method f(). So if the
// code will not compile, why warn about the potential for such code to exist?
#pragma warning (disable: 4284)
// often, we have local variables for the express purpose of ASSERTion.
// when compiling retail, those assertions disappear, leaving our locals
// as unreferenced.
