Compilation warnings with HP aCC compiler under HPUX 11iv3 (ia64 arch.)

[sfotis]

This is the list of warnings produced by HP's compiler under a headless (thus no X11) HPUX 11i v3 system.

Due to the size limit i used pastebin

A lot of these warnings seem to be similar to those in #286. Looking at some of the OCCT git logs and the cdl files, it looks like the majority of the virtual function overrides are intentional.

Looking at the warnings, I think the key issues here are the NULL references and the possible misaligned accesses. Everything else looks trivial.

@sfotis Any chance you could re-compile using the latest master? A lot has changed since last October and so line numbers have changed, etc.

A lot of these NULL references are going to get fixed by OCCT related to #520.
