/* This header file provides three OS-specific macros for the definition of
extern (or NOT extern) symbols:
* PUBLIC, which has to be used to mark objects that will be used
outside the module
* INTERN, for symbols which are shared among compilation units within a
module, but are NOT exported to other modules.
* PRIVATE, for symbols which are visible only within the containing
compilation unit (i.e. C source file) and, of course, are not exported to
other modules.
Please don't add "extern" after the PRIVATE or PUBLIC declaration
as this would break compilation on Darwin.
