/*-------------------------------------------------------------------------
 * Purpose:	Register function entry for library initialization and code
 *		profiling.
 *
 * Notes:	Every file must have a file-scope variable called
 *		`initialize_interface_g' of type hbool_t which is initialized
 *		to FALSE.
 *
 *		Don't use local variable initializers which contain
 *		calls to other library functions since the initializer
 *		would happen before the FUNC_ENTER() gets called.  Don't
 *		use initializers that require special cleanup code to
 *		execute if FUNC_ENTER() fails since a failing FUNC_ENTER()
 *		returns immediately without branching to the `done' label.
