+// Platform specific code to invoke XPCOM methods on native objects

+// access. The parameters for the method are read from the
+// nsXPTCVariant* and prepared for th native ABI.  For the Linux/PPC
+// ABI this means that the first 8 integral and floating point
+// parameters are passed in registers.
