[VXWORKS PPC 2.95.3] vxworks-redef.patch




  One of the VxWorks header files defines _BIG_ENDIAN, which is also
defined in rs6000.h, causing a spurious redefinition error.  We could
either remove the #define in the header file with fixincs, or remove the
predefine from the specs; I chose this approach because it still works
with unfixed VxWorks header files, which may happen since default VxWorks
makefiles include the -nostdinc flag.
