// Convenience macros for checking null-ness of pointers.
//
// Purportedly, gtest should support pointer comparison when the first argument
// is a pointer (e.g. NULL). It is therefore appropriate to use
// {ASSERT,EXPECT}_{EQ,NE} for our purposes. However, gtest fails to realize
// that NULL is a pointer when used with the _NE variants, unless we explicitly
// cast it to a pointer type, and so we inject this casting.
//
// Note that checking nullness of the content of a scoped_ptr requires getting
// the inner pointer value via get().
