E.1.4.5 (188.8.131.52) The value of an integer character constant that contains a character or escape sequence not represented in the basic execution character set or the extended character set for a wide character constant:
E.1.5.2 (184.108.40.206) The result of converting an integer to a shorter signed integer, or the result of converting an unsigned integer to a signed integer of equal length, if the value cannot be represented:

The ISO/IEC 9899:1990, Programming Languages- C standard specifies the form and establishes the interpretation of programs written in C. However, this standard leaves a number of issues as implementation-defined, that is, as varying from compiler to compiler. This chapter details these areas. They can be readily compared to the ISO/IEC 9899:1990 standard itself:
Each item uses the same section text as found in the ISO standard.
Each item is preceded by its corresponding section number in the ISO standard.
