I was remembering incorrectly. projPJ is a typedef that is really  
either PJ *, or void *, depending on whether PROJECTS_H is defined.  
And this is defined if you include projects.h before the main proj  
include file. As I never access the inside of the struct, I do not  
include projects.h. But it seems to be needed if you want to access  
the inside of the struct.

Sorry for the confusion.

It is RSofT and there is always something under construction.
It is like talking about large city with all constructions finished.
Not impossible, but very unlikely.
