Hide memset/bzero from compiler 

Hide memset/bzero from compiler to silence Clang error:

./tester.c:1345:29: error: 'size' argument to memset is '0'; did you mean to transpose the last two arguments? [-Werror,-Wmemset-transposed-args]
 1345 |   (void) memset(one+2, 'y', 0);
      |                             ^
./tester.c:1345:29: note: parenthesize the third argument to silence
./tester.c:1432:16: error: 'size' argument to bzero is '0' [-Werror,-Wsuspicious-bzero]
 1432 |   bzero(one+2, 0);
      |                ^
./tester.c:1432:16: note: parenthesize the second argument to silence
