<P><B>Note:</B> <A HREF="#CHAR_MAX">CHAR_MAX</A> and <A HREF="#CHAR_MIN">CHAR_MIN</A> may have different values depending on whether chars are signed or not.
They are signed by default in GCC4TI, but this may be changed using a compiler command-line switch.
Similarly, <A HREF="#INT_MAX">INT_MAX</A>, <A HREF="#INT_MIN">INT_MIN</A>, and <A HREF="#UINT_MAX">UINT_MAX</A> depend on whether short or long integers are used.</P>
