The explanations of const, and when it can be used I've found so
far are dated 1995 and refer to ANSI standard.

But then if I knew much about this I wouldn't be asking such
silly questions.

For Steve - I want small read only arrays like

pi5digits[5] = { 3,1,4,1,5 };

Which currently occur before main(), and are labelled extern in
a shared header file, so they can be used from anywhere.

My mistake was messing with "static" I think. 

I'm not sure if marking them read-only ("const") will speed
things up, but I figure it has to make it easier to find bugs,
and it has to give the compiler a clue.
