It is real (under certain topologies), and it is not normal (otherwise 
everything will break).  I don't see how this can be up for debate...

It is embedded in the current code as being special.  This is fine in 
the current code, since it is never a real position.  But it leads to 
problems when it can be a real position because then its definitions as 
"real-but-not-normal" and "special" conflict.
