title: Should I Suppress? If so How To Suppress from Makefile
body: <p>I have several tests that run and in the end I run Valgrind to verify my libraries memory usage. Valgrind consistently complains about:</p>

  <p>These do not seem to be related to my library. Should I be concerned about theses warnings?
  Or should I be making an attempt to suppress these leaks? If I should suppress what would be the cleanest way to do this from a Makefile?</p>
