PR 595/tests * sp13/fillbuff.c, sp13/init.c, sp13/putbuff.c, sp13/system.h, sp13/task1.c, sp13/task2.c: Fill_buffer() in fillbuff.c overruns the supplied buffer due to confusion in the definition of MESSAGE_SIZE. Some files in the sp13 test treat MESSAGE_SIZE as a count of bytes, others treat it as a count of longs.
