The "powerpc" port which has supported the newer Apple Macintosh powerpc based
is being renamed to macppc. This is to allow sharing of common code between different powerpc base platforms. Most of the work involved in the renaming process was performed by miod@ Files moved from powerpc/include to macppc/include Some files were not "moved" but wrapper files were created which include the powerpc/include version. Several of the powerpc/include files where changed to reflect that they are POWERPC_* not MACHINE_*.
