Typedefs
The uchar_T, ushort_T and ulong_T types are needed for compilers which do not allow defines to be specified, at the command line, with spaces in them.

typedef UINT16_T	CHAR16_T
Fixed width word size data types: int8_T, int16_T, int32_T - signed 8, 16, or 32 bit integers uint8_T, uint16_T, uint32_T - unsigned 8, 16, or 32 bit integers real32_T, real64_T - 32 and 64 bit floating point numbers It is common for one or more of the integer types to be the same size. For example, on many embedded processors, both shorts and ints are 16 bits. On processors used for workstations, it is quite common for both int and long to be 32 bits. When there is more than one choice for typdef'ing a portable type like int16_T or uint32_T, in concept, it should not matter which choice is made. However, some style guides and some code checking tools do identify and complain about seemingly irrelevant differences. For example, a code checking tool may complain about an implicit conversion from int to short even though both are 16 bits. To reduce these types of complaints, it is best to make int the preferred choice when more than one is available. The following is used to emulate smaller integer types when only larger types are available. For example, compilers for TI C3x/C4x DSPs define char and short to be 32 bits, so 8 and 16 bits are not directly available. This target is commonly used with RTW rapid prototyping. Other DSPs define char to be 16 bits, so 8 bits is not directly available.

Data types for use with MATLAB/SIMULINK and the Real-Time Workshop.

When compiling stand-alone model code, data types can be overridden via compiler switches.

Define NO_FLOATS to eliminate reference to real_T, etc.

_

When used with Real Time Workshop generated code, this header file can be used with a variety of compilers.

The compiler could be for an 8 bit embedded processor that only had 8 bits per integer and 16 bits per long. In that example, a 32 bit integer size is not even available. This header file should be robust to that.

For the case of an 8 bit processor, the preprocessor may be limited to 16 bit math like its target. That limitation would mean that 32 bit comparisons can't be done accurately. To increase robustness to this, comparisons are done against smaller values first. An inaccurate 32 bit comparison isn't attempted if the 16 bit comparison has already succeeded.

Limitations on preprocessor math can also be stricter than for the target. There are known cases where a compiler targeting processors with 64 bit longs can't do accurate preprocessor comparisons on more than 32 bits.
