// Carbonization
// -------------
// The problem:
// The Carbon API requires that we treat Toolbox data structures as opaque --
// that we not access their members directly, but use accessor functions.
// Since we'd like to use the same code across API targets, we'll use these accessors
// for pre-Carbon Mac OS as well as Carbon. Some of the Carbon accessor functions
// are defined as inline functions in the Universal Interfaces for just this purpose,
// but some are not. For these, we define our own macros.
// This file must be included AFTER ConditionalMacros.h. To make life simple,
// we include it.
