  61
  62 <p>When a make clobber is performed in sys the make is propagated downward through the sub makes. However the sys level Makefile starts it's clobber target with: rm $(ENV_PREFIX)/sys/lib/* to remove all of the libraries in sys/lib.</p>
  63
  64 <p>When the make clobber gets propagated down to drivers/arinc653 the following happens:</p>

 112 <p>This eventually screws up the build. Doing a make clobber followed by rm lib/* then a make install works OK...</p>
