12722 that the compiler uses to store them. Explain and make examples
12723 of how 'const' interacts with pointers, and the complication of
12724 the encoding of 'const char *'.

12726 incorrect type encodings for the NeXT runtime for compatibility
12728 (@@encode): New subsection, explaining @encode and particularly
12729 that protocol qualifiers are not recognized inside an @encode()
12731 (Method signatures): New subsection, explaining how method
12732 signatures are encoded.
