Regarding the placement of string literals, the following question
came up in de.comp.lang.c:
 
Obviously, there are compilers that handle
 
   char *foo = "Hello world";
 
different form
 
   const char *bar = "Hello world";
 
as far as the placement of the string literal is concerned. String   
literals are arrays of "const char". This implies that they can
be placed in read only memory. Does the definition of "foo" somehow
prevent this placement?

In other words, what is wrong with the statement: "String literals
are arrays of const char, and hence may be placed in a read only 
region of storage, even if they are used to initialize a non const
char *"?
