Why was 2's complement and RTWTYPES_ID guards removed from ERT code in 2013B?

Prior to 21013B rtwtypes.h included compiler snippets that would cause compile time errors if code used had been generated with different type definitions (RTWTYPES_ID) and checked that the compiled code supported correct 2's complement operation.
#if ((SCHAR_MIN + 1) != -SCHAR_MAX)
#error "This code must be compiled using a 2's complement representation for signed integer values"
#endif
These seemed to be reasonable and useful checks - why were they removed from the code generated in 2103B and forward?
