// Pay attention to the macro definitions for the macros you wish to
// modify. For example, only macros categorized as compiler macros should
// appear in this file; platform macros should not appear in this file.
// Also, some macros have to be defined to specific values; it is not
// always enough to define or undefine a macro.
//
// Macro definitions are available in the source code at:
