Don't worry - its handled in r255905 (hopefully not breaking any buildbots 
on the way).

I additionally improved the handling of warning switches 
(-Wdelete-non-virtual-dtor is no in there now and -Wnon-virtual-dtor is not 
for gcc builds only).  I will also close out the bug -- it is true that I 
had only used the -Wnon-virtual-dtor warning in my testing and had not 
realised that the other warning existed!!

Cheers, and thanks for your patience.
