Predefined Macros
=================

   Several object-like macros are predefined; you use them without
supplying their definitions.  They fall into three classes: standard,
common, and system-specific.

   In C++, there is a fourth category, the named operators.  They act
like predefined macros, but you cannot undefine them.
