title: How to go about adding unit tests to an established (autotools) C project
body: <p>I have a fork of openssh with some new features and want to write some unit tests to make sure they work at build. Grafting Check into openssh's autotools configuration is diffacult (because I don't really understand autotools)</p>
  
  <p>Is there an easier to use C unit test framework? One less closely tied to autotools? 
  How about a better way of going about adding Check to this project with out radically changing its build files? </p>
