Various platform-dependent constants proposed by ANSI
Note: CHAR_MAX and CHAR_MIN may have different values depending on whether chars are signed or not. They are signed by default in TIGCC, but this may be changed using a compiler command-line switch. Similarly, INT_MAX, INT_MIN, and UINT_MAX depend on whether short or long integers are used.
