[SF Markus Elfring]

> Could you please be more specific?
Yes, of course.
It seems that it was forgotten to use the const specifier for read-only 
arrays in most of the source files in the Asterisk application directory.


> Could you please point to one specific place in the code?
>   
Would you like to look at the variable variations like "app", "synopsis" 
and "descrip"?
