This diff includes changes for the remaining _Fract and _Sat fixed point types. ``` signed short _Fract s_short_fract; signed _Fract s_fract; signed long _Fract s_long_fract; unsigned short _Fract u_short_fract; unsigned _Fract u_fract; unsigned long _Fract u_long_fract; // Aliased fixed point types short _Accum short_accum; _Accum accum; long _Accum long_accum; short _Fract short_fract; _Fract fract; long _Fract long_fract; // Saturated fixed point types _Sat signed short _Accum sat_s_short_accum; _Sat signed _Accum sat_s_accum; _Sat signed long _Accum sat_s_long_accum; _Sat unsigned short _Accum sat_u_short_accum; _Sat unsigned _Accum sat_u_accum; _Sat unsigned long _Accum sat_u_long_accum; _Sat signed short _Fract sat_s_short_fract; _Sat signed _Fract sat_s_fract; _Sat signed long _Fract sat_s_long_fract; _Sat unsigned short _Fract sat_u_short_fract; _Sat unsigned _Fract sat_u_fract; _Sat unsigned long _Fract sat_u_long_fract; // Aliased saturated fixed point types _Sat short _Accum sat_short_accum; _Sat _Accum sat_accum; _Sat long _Accum sat_long_accum; _Sat short _Fract sat_short_fract; _Sat _Fract sat_fract; _Sat long _Fract sat_long_fract; ``` This diff only allows for declaration of these fixed point types. Assignment and other operations done on fixed point types according to http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1169.pdf will be added in future patches.
