compiler documentation error

In the TMS320C55x Optimizing C/C++ Compiler v 4.4 User's Guide, SPRU281G, section 2.3.3 refers to a switch prtrdiff_t_16 to set the size of the standard C type ptrdiff_t to 16 bits. At the very least there is a spelling error, it should be ptrdiff_t_16, but more importantly ptrdiff_t_16 seems to be deprecated. Table 2-11 mentions --ptrdiff_size=16 instead of ptrdiff_t_16, the compiler help text obtained by running ccl55 without options mentions --ptrdiff_size, but not ptrdiff_t_16. CCS uses --ptrdiff_size.
