``` // Primary fixed point types signed short _Accum s_short_accum; signed _Accum s_accum; signed long _Accum s_long_accum; unsigned short _Accum u_short_accum; unsigned _Accum u_accum; unsigned long _Accum u_long_accum; // Aliased fixed point types short _Accum short_accum; _Accum accum; long _Accum long_accum; ``` This diff only allows for declaration of the 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. The saturated versions of these types and the equivalent `_Fract` types will also be added in future patches. The tests included are for asserting that we can declare these types.
