+	* HOST machine-dependent predefined macros
+	  __MCPU_HOST_MACHINE_REGISTER_WIDTH__,
+	  __MCPU_HOST_MACHINE_SIZEOF_SIZE__, __MCPU_HOST_MACHINE_SIZEOF_SSIZE__,
+	  __MCPU_HOST_MACHINE_SIZE_MAX__, __MCPU_HOST_MACHINE_SIZE_TYPE__,
+	  __MCPU_HOST_MACHINE_SIZE_WIDTH__, __MCPU_HOST_MACHINE_SSIZE_MAX__,
+	  __MCPU_HOST_MACHINE_SSIZE_TYPE__, __MCPU_HOST_MACHINE_SSIZE_WIDTH__
+	  are not part of the MCPU ABI but can be used in guest programs to
+	  obtain HOST-specific sizes and the corresponding MCPU HLL data types.
+	* LibMPU 1.0.28, LibMPUIO 1.0.8 are required.
