All objects are still allocated from a private storage (called heap), -but now the heap serves properly aligned memory chunks. Implementation of the heap is (hopefully) platform -independent, so all <code class="docutils literal notranslate"><span class="pre">ARM_COMPLIANT</span></code> checks has been removed. Some details work differently on 32/64-bit -machines, this distinction seems inevitable.

So far <code class="docutils literal notranslate"><span class="pre">pplib</span></code> uses only the <strong>heap</strong>, but I want to have this part -in a single place for a while.
